How's going on guys right? It's mark and I thought I'd do a quick video just on one of my favorite stocks that I've Picked out for this week, and I've got my eyes on coincidentally. I also have my goofy ones You know which is purely by I'm not gonna keep this up the whole time, but it's purely by Coincidence it happens to be Disney That I'm looking at and I like the look of so first of all Before we trade anything. I just like to have a quick look at Whoops, no, I don't do that some of the news that's come out, right? So if you don't know how I do this, I'm just going nasdaq.com And then go on to company headlines after you've searched company. Nothing is Particularly jumping out in terms of you know good or bad news, which is nice. I like that Nothing that's gonna massively act as a catalyst that I can see anyway It's all just kind of general news. I'm about the market that's been mentioned in Which is good So what that means for me anyway is that I can rely a little bit more on the technicals Technical side of things. So if you have a look Disney since kind of around July has been traded in between kind of one one or nine one ten and one seventeen So these two levels here right and obviously it's had a bit of a harsh pullback all the way to a hundred And where you can see it's consolidated previously If I just whack that up and draw that in Boom, you see so it's consolidated at hundred previously also was a previous resistance. So someone can mind So yeah, but that's that's not in terrible incredibly scary Also, if you don't know how I set my charts up with the EMA SMA MacD and RSI I do have a link in the description to kind of house that all up and things and be a so you can see that It's been trading between this range for a while now You can see I've already got a small small position about three percent the account in there The only thing that I need it to do now before we kind of commit a little bit more is break Above this SMA because you can see the SMA has acted as a resistance before right here. I'm here I'm a little bit here for a pullback and then then pushed up And you can also see that it's acted as a support before right so here here And obviously all supports new resistance and so on so we want to we want to see a break about the email Excuse me SMA before we kind of massively go into it But I'm a little bit involved right now just because it's broken above the EMA is hold is held that position here and the RSI looks good It's it's at a good level and the MacD is curving in for a buyer So hopefully with the EMA curling around and the SMA is also looking kind of positive or neutral, which is good It's not it's not actively kind of sloping down Yeah, so I'd hope Conservatively for it to push up to this kind of one 14 mark Which would be about a five six seven eight percent game or no I think about five or six and then we've if it if we was to kind of be a bit more aggressive and hold on to 117 and that'll be about seven or eight, which is you know if in my opinion pretty good So yeah, that's that's all there is to it really I just thought I'd make a quick video and point this one out Also over the long term Disney has You know pretty solid uptrend So always happy to trade things that you know trend upwards and then try and buy at the low sell at the highs That's the aim of the game. So yeah, just quick one just break down of Disney for now, and I just wanted to highlight that probably gonna be getting a bit more involved with this As it kind of trends up If it does continue to pull back or there's a bit of a sell-off again We've seen it at this hundred level pretty consistently where it did right down before here, but then also consolidated before so Nothing too scary wouldn't be too worried Unless there's something dramatic that happens, but I think it's a pretty good one to buy into So let me know what you think of Disney Let me know what you have your eyes on what stocks you're kind of keeping keeping in your watch list If you enjoyed the video give it a like if you didn't like the video Give me a thumbs down. Tell me why you didn't like it Yeah, subscribe if you enjoyed share and all that kind of good stuff. So thanks for watching guys and I will oh Wait, let me do it. Yeah, Joe. I'll catch you Probably tomorrow Tesla's been doing quite good as well. So just as I don't probably be picking that up or making videos about that Anyway, later on thanks for watching. Bye


Let's play ball. Soldiers from Attack Company 1st Battalion 503rd Infantry Regiment of 173rd Airborne Brigade put down their weapons and put on their gloves for a game against the Latvian National Baseball Team. The 1st Iraq troops are in Latvia supporting Operation Atlantic Resolve, an ongoing partnership that focuses on joint training and security cooperation between the U.S. and NATO allies. The soldiers were able to take a break from training and enjoy a piece of home. It's pretty cool to see that our pastime has made it all the way this far across the world and really interesting on how actually good they are and their fundamentals and everything were. The friendly match proved to be a fair one as both teams went back and forth for the lead. The Latvian National Team would come out on top 11-7. The competitive spirit was alive and well on each side but the relationship developed between the two countries was the real winner. For us it's important to show that we are like friendly and we are welcome American troops here and it's really good and we appreciate that and that's one way of showing too. Just having a friendly game and just hanging out and I think it's a great thing to do. Reporting from Riga Latvia for the U.S. 16th and Pad, I'm Army Sergeant Summer Wood.


Okay. So, good day everybody. So, welcome to our discussion for today. So, our discussion on hematology too will be starting on an introduction to hemostasis. Again, good morning to everybody and I hope everybody has their product with them right now. So, as for your reading assignment, okay, reading assignment or you can just simply follow along when I'm discussing will be your products hematology 2020, the 6th edition. So, please turn to chapter 35 and let us talk about normal hemostasis. Specifically, the one that I'll be discussing for today is found on pages 626 to 627, specifically the overview to hemostasis. So, last time during our orientation, okay, last time during our orientation, I already gave you an overview of the hemostasis. So, we said that hemostasis is very important because it preserves your blood in its proper compartment at a proper face at the, at a proper face at the right time. So, I always tell you that the blood should be in a liquid form or the blood should coagulate, okay, the blood should coagulate at a perfect time, at a perfect place and for the right purpose. So, for this particular discussion on your screen right now, so we're going to talk about hemostasis. So, when we talk about hemostasis in general, this is the process in which, it is the process in which the blood is retained within the vascular system during period of injury or it localizes the reaction involved to the site of injury alone and it will not be a systemic bleeding. So, remember that, take for example, you have your bone, you have your wound. So, we want as much as possible to localize the bleeding on that part so that it can be addressed immediately, it can be stopped immediately by our body, okay. But always remember, okay, always remember that hemostasis doesn't just only is concerned when it comes to our blood being in its liquid form, when it is within our blood vessel but it is also responsible in maintaining coagulation once the blood escaped from your blood vessel. At the same time, just like what I told you last time, our ultimate goal is to stop the bleeding, to address the injury and also for tissue repair to happen and after that we can now re-establish the blood flow but before that happens, fibrenolysis should take place first, okay. So, your hemostasis is a system, okay, a system that is very much important to be maintained within our blood, that's why we call it hemostasis. So, as you all know, your blood, your only liquid connective tissue when inside the blood, there should not be any coagulation. So, it should remain fluid, it should be liquid in state when inside our blood vessel, this is for blood flow to happen, that can yet be delivered, your oxygen been delivered all across your tissue and at the same time, when now your blood is outside your blood vessel, when does your blood escape from your blood vessel? So, this is during injury, okay, this is during injury or during tissue damage whereby there is an involvement of your blood vessel, so once that your blood is outside the blood vessel, it needs to coagulate, okay, it's need to coagulate, so here is the time now where your hemotactic reaction happen, all of your coagulation factors, both all the components of your primary and secondary hemostasis which we are going to talk about in a short while will all be involved, okay, so that is the normal state, your blood being liquid when inside your blood vessel and when outside the blood vessel, it should be coagulating, okay, so to prevent further loss of blood. Now, the problem is that there are some hemostasis abnormality, okay, abnormal mechanism inside our body that may cause the opposite of what I just mentioned to you a while back, so what happened is that, what happened when your blood is inside your blood vessel and it coagulated, then that's the problem now because it would need to thrombosis diseases, okay, thrombosis diseases, so the result of excessive blood formation inside your blood vessel or persistence of blood inside your blood vessel can lead to thrombosis, so they can occlude their blood vessel, therefore your oxygen cannot pass through, your nutrients cannot pass through that organ or that particular part of your body will be deprived of nutrients and it would eventually be damaged or it can even lead to cell death. Now, on the other end of the spectrum, if your blood demand is outside your blood and there's also abnormal mechanism, so sabi datin dapat pag, if it is already outside the blood, then it should be coagulating, but the problem is if that didn't happen, okay, there is no coagulation that happened, bleeding will persist or what we call now these are your hemorrhagic diseases. So the problem here, this type, is that when there are any procoagulant, meaning to say, proteins that favor the coagulation of our blood, like your coagulation factors, if there are procoagulants that are missing, deficient in a particular individual, then okay, what will happen is that there would be an uncontrolled bleeding, so your patient will just bleed and bleed all throughout, there will be severe blood loss, and there will be hemorrhage that will also lead to death. So in a nutshell, it's very important that our blood should be maintained in its liquid form inside the blood vessel and when the blood escaped from your blood vessel, it should be coagulating. So this particular mechanism is very much maintained, did usually, inside our body. So at the very moment that your blood escaped, a lot of your proteins will also ready to be released to favor coagulation, but at the same time, there are also inhibitors that will be secreted so to ensure that your blood, your blood will not be coagulated. Excessively, there will not be thrombus formation or clot formation anywhere in your body. Again, always remember, the clot should happen at the right time, at the right place, and at the right, for the right purpose. Okay, so in addition to that now, okay, when we talk about hemostasis, it's not just a job of your, it's not just the job of your platelets, although platelet is one key player, but platelet is not alone, so for us to be able to understand how hemostasis happen, we will also be talking about today the different key components of hemostasis which are as follow. So there are two general classification of the different components of hemostasis. First are the cellular components and second are the plasma components. So when we talk about cellular components, these are now the cells of your vascular intima. To be more specific, these are your endothelial cells. Okay, this will be part of our discussion in the coming weeks when we will be talking about your vascular intima. Next, we also have your vascular tissue factor bearing cells. So very simple. All of your tissue cells that can produce or that contains your tissue factor is included here. Okay, so they secrete a very important coagulation factor, coagulation factor three, which is your tissue factor. Also favoring your coagulation. And of course, last but definitely not the least, we have your platelets, your platelets being one of the key cellular components for your hemostasis. As for the plasma components, we also have your coagulation proteins. Your coagulation proteins, these are the proteins that favor coagulation. You can also read this in your rodac as pro-coagulant or in other words, they are also called your coagulation proteins meaning to say once that they are present and activated inside your body, they will favor coagulation. At the other end, we also have your fibrolytic proteins. So remember, I told you last time that when it comes to fibrolytic proteins, these are proteins now that will elicit or that will trigger the lysis or that will hasten the clot to be dissolved inside your body. So once the tissue repair is on its way, the clot that has been formed will now have to be lice or now have to be destroyed and be cleared out of your blood vessel. How? That is through the health of your fibrolytic proteins. Now, aside from coagulation proteins and fibrolytic proteins, coagulation, one that promotes coagulation, fibrolytic, the one that the group of proteins that will lice or destroy now or dissolve your clot, we also have your inhibitors. Inhibitors now are the one that inhibits your coagulation proteins. For example, there is a bystander clot formation inside your blood vessel. There is no need for clot formation to happen but it happened. So your inhibitors now will prevent the coagulation from further developing into a stabilized clot. On the other end, you also have your inhibitors for your fibrolytic proteins. What is the purpose of these inhibitors? The inhibitors of your fibrolytic protein. So remember, fibrolytic proteins should only be activated once that tissue repair is about to happen. That is to clear out the clot, that is to clear out the passage of the blood and kung hindi pa tapos, if the repair is not yet done, if the blood vessel is still healing, the clot should remain there. Do not remove the clot if it's not yet time. Take for example, your baking cake in the oven and then you remove it under time. You did not wait for 30 minutes, just remove it after 5 minutes. Of course, that is uncooked. So to be able to inhibit, for you to ensure that it will be cooked, you have to put some inhibitors. For example, the oven cannot be opened until the timer is done. Inside our body, it's also very similar. We have inhibitors that will prevent fibrolytic protein from destroying the clot if it's not yet time to be destroyed. So these mechanisms happen inside our body in a very close and tedious manner so that we will be able to prevent the clot from being destroyed unknowingly. And we'll be able to prevent it from being destroyed na wala pang t-shirt repair na nangyari. So apologies for that quick commercial. Aside from the components of your hemostasis being classified as cellular components and plasma components, we can further classify them according to where they belong. So some belong to your primary hemostasis, some belong to your secondary hemostasis, and now your fibrolysis. So these are the processes of your hemostasis. So let's first talk about your primary hemostasis. So when we talk about primary hemostasis, primary hemostasis is usually activated by small injuries to blood vessels. So primary hemostasis is very rapid yet short lived response. So this is just like a first aid scenario inside our body. So it is very rapid, once there is a small injury in the blood vessel, it is the first one to be activated, but it is short lived. So what are the components of your primary hemostasis? So the components are your vascular system, starting off from the smallest blood vessel that we have, which are your what? Which are your capillaries, also included here are your arteries, and of course your veins as well. So what important thing that I want you guys to remember is that the main component responsible for the primary hemostasis specifically for your vascular system are your vascular intima.  So when we say endothelial cell, endothelium, and vascular intima, which is the innermost layer of your blood vessel, vascular intima, which are all made up of your endothelium, that is component that is part of your primary hemostasis. At the same time, we also include your platelets, okay? We also include your platelets. So let's have a quick quen to how does it happen. So for example, how does your primary hemostasis happen? So as you all know, once there is a small injury, the vascular system would contract to seal the wound, and that is the initial hemotactic response that is your vasoconstriction. So remember that people, the initial hemostatic response of our body, specifically our vascular system, is your vasoconstriction. Vasoconstriction helps so that we can seal the wound, we can seal the wound and prevent further or excessive loss of blood, but that will not be enough. Why? Because we also need to have your platelet plug. So your platelet plug, okay? Your platelet plug is, of course, made up of your platelet that fill the open space of your wound, so that is to form your platelet plug. So remember that the innermost vascular lining of your blood vessel, your vascular intima, are aligned by your endothelial cells.  Once they are activated, they will adhere to the site of injury. So as you can see here, your platelets now started to adhere to the wound or to the blood vessel wound. Aside from that, I also want you guys to remember that on your subendothelial, remember that your blood vessel has layers, right?  And the innermost layer of your blood vessel also interacts.  And also smooth muscle and your artery. These are your arteries. If it's just your veins, these are only your collagen and fibroblast. Sir, why is your fibroblast important? Your fibroblast is important when it comes to the repair part of your blood vessel. So they are the one that will produce new set of cells that will close the blood vessel, okay? But to summarize everything that I just mentioned about primary hemostasis and what once that there is a small injury and the blood vessel, a rapid and a short response called your primary hemostasis will take place. Again, the key player of this or your vascular system and your platelet, how does they prevent your bleeding? They prevent bleeding by first sealing, okay? The wound, how do they seal the wound by the initial hemostatic response, which is your vasoconstriction? And afterwards platelet will fill in the gap or will fill in now the open space coming from your wound producing a platelet plug. And your platelet plug in other books, you can read it as your primary hemostatic plug, okay? Your primary hemostatic plug. Your primary hemostatic plug ladies and gentlemen are mainly made up of your platelets alone, okay? Let me repeat that. It is only your platelet. Why? Because we are still in the primary hemostasis. So, meaning sir, there is a more advanced or a better, a more advanced or a secondary response after your primary. Yes, that's very correct. Your primary hemostasis is the first aid. It is the first thing that would happen followed by your secondary hemostasis. Secondary hemostasis will now be activated once that the primary hemostasis response is not enough. How would that be or when are the times that it's going to happen?  Like, for example, there is really a big wound, okay? Your blood vessel was caught. So, lots of blood will be coming out or will be, lots of blood will be, will escape your blood vessel. So, when it comes to your secondary hemostasis, this is activated again by a large injury of your blood vessels. This is a delayed response, okay? But the good thing about this is that it is a long-term response, okay? It is a long-term response. So, the following components of your secondary hemostasis are as follow. So, components are your coagulation factors, your coagulation inhibitors. So, your coagulation factors are those that promote coagulation. We also call this your procoagulance and your coagulation inhibitors. Obviously, these are their inhibitors. So, to prevent any unwanted clot formation inside your blood vessels, okay? So, to prevent any unwanted blood, to prevent any unwanted clot formation in the body, they're also coagulation inhibitors, okay? Coagulation inhibitors that are also found in your blood. So, to prevent any unwanted coagulation, okay? Any coagulation. So, with that, okay, let's also talk about how does the secondary hemostasis happen. So, the secondary hemostasis happened by the interaction of your coagulation factors. So, to produce fibrin clot, okay? Your fibrin clot, which is what we call now your secondary hemostatic clot. Remember that in the primary hemostasis, the end product there will be a platelet clot, a platelet clot that will prevent bleeding. That is your primary hemostatic clot. And now, for your secondary hemostasis, we have now the interaction of your coagulation factor. So, I'll part this. I won't be discussing the coagulation factors yet because we will be discussing that around the fifth week before the fifth week of our discussion. And we will also be talking about the coagulation cascade, okay? It is a pathway in which your proteins are activated simultaneously one after the other to produce now your fibrin clot. Remember that your fibrin clot is from the activation of your factor one or your fibrinogen. Fibrinogen becoming your fibrin, okay? Your fibrinogen now becoming your fibrin. And the ultimate protein, okay, or the ultimate enzyme that we want to produce there is your thrombin. Thrombin now will be the one to convert your fibrinogen to fibrin, paking it now or producing now a fibrin clot. So, as you can see, once that the secondary hemostatic clot happened, okay, it needs to be stabilized. And it will be stabilized by your factor 13, which is now your fibrin stabilization. So, if you guys can see, no, if you guys can see your screen right now, initially, okay, initially, once that there is a damage here, okay, the first thing that will always happen will be your primary hemostasis.  Once that it will not, once that their effort is not enough, that's the time that the secondary hemostasis will be activated. These are now your coagulation factor. Your coagulation factor will form your fibrin clot.  But your fibrin clot needs to be further stabilized as to prevent it from breaking, okay, that is now through the help of your factor 13. Okay, that is now through the help of your factor 13. You guys don't worry because will be, this is just an overview of hemostasis. In the coming days after your mega-choreocytopoiesis will be discussing the components of your primary and your secondary hemostasis and talk about more about how they happen and what are the other neat and gritty details about these processes. And finally, we also have your fibrenolysis. Now, in your fibrenolysis, remember that this is now the final stage of coagulation. Fibrenolysis will only happen once that the wound is sealed and now we are ready to repair the blood vessels. So this is the final stage of coagulation. So as you can see, there will now be thrombolysis. Thrombolysis or your fibrinolysis is one and the same. As you can see, there are a lot of proteins, okay, there are a lot of proteins that will digest your fibrin clot. So the digestion of your fibrin clot keeps the vascular system free of deposited fibrin or fibrin clot. Why? Number one, deposited fibrin and fibrin clot will clog your blood vessel, okay? Barado ang ating blood vessel if the fibrin will not be removed. Aside from that, fibrin and fibrin and fibrin clot, okay? Your fibrin or your fibrin clot can also cause, okay? Can also cause, ayo, nabangkit ko na, deposition, okay? Deposition of clot inside your body that will cause clogging, okay? So your fibrinolysis occurs when your plasminogen is converted to plasmine. So plasminogen is zymogen, meaning to say an inactive enzyme. So once that it is activated, okay? Once that it is activated by your thrombine, it will now be converted to plasmine, okay? So your plasmine will now be the one that will lyse your fibrin clot, okay? It will lyse your fibrin clot. Remember that the cleaving or the digestion of your fibrin clot is very important, okay? It's very important. So under normal circumstances, your plasminogen is just a part of any clot, okay? As to, ayo, because of the tendency of your fibrin clot to absorb plasminogen from the plasma. So when the time is right, okay? When the time is right, when your plasminogen activators perform their function, your plasminogen now will be converted to plasmine and your plasmine now will start to clean up, will start to digest your clot while leaving time for tissue repair to happen and re-establishing the blood flow, okay? Re-establishing the blood flow. So how does your fibrinolysis happen? So first, release of tissue plasminogen activators and then the plasminogen will be converted to plasmine. Now your plasmine will degrade or digest your fibrin converting them, okay, to fibrin degradation products. Your fibrin degradation products will be talking about that on the latter part of our rheumatology too. But hopefully you understood the concept of hemostasis. So from primary hemostasis, so let's have a quick review lang mo, from primary hemostasis, okay? So in primary hemostasis, what's the first thing that happened? Okay, the first thing that happened, if there any injury in your blood vessel, it will first, the initial hemostatic response, it will lead to what? It will lead to vasoconstriction. So after vasoconstriction, okay, your platelets now will be exposed to your collagen and your elastin. It will attach to that, okay? And then it will now fill up the gap or the wound as to prevent bleeding. If that's not enough, your secondary hemostasis will be activated. And how it is activated, it is through the activation of your coagulation factors. Coagulation factors that will lead to the formation of your fibrin clot. Now once your fibrin clot is produced, okay? Once that your fibrin clot is produced, it will remain there for as long as it is needed. But let us assume that the task is already finished. We will now be entering the final stage of your coagulation, which is your fibrinolysis. And in your fibrinolysis, a protein called your plasmidogen will be converted, will be activated to become your plasmidogen.  Okay? Or your fibrin clot to their degradation products. Okay? Your fibrin degradation product and will now re-establish your blood flow. So I prepared a very, very quick picture here. So when there's injury, okay, there will be vasoconstriction. And at the same time, platelets, okay, will adhere to the wound, will fill up the gap. So that is primary hemostasis. If this once is not enough, okay, your coagulation factors, okay, your platelet plug will not be enough. Your coagulation factors will be activated, forming now your fibrin clot. Okay? Once that's finished, repair is on its way. We need to re-establish the blood flow. Fibrinolysis now will happen. So remember, guys, okay, remember, guys, few things. You should be able to remember the three important stages of hemostasis. Your primary secondary hemostasis and your fibrinolysis. Second, what are the different cellular and plasma components belonging to your primary hemostasis. Your secondary hemostasis and your fibrinolysis. Finally, I also want you to remember what three things, okay, before we end this particular part of our discussion. What is the initial hemostatic response that is vasoconstriction? Okay, second, what is the primary, what is the other name of your primary hemostatic plug that is your platelet plug? Okay, that is your platelet plug. And finally, what do you call the secondary hemostatic plug that is your fibrin clot? What stabilizes your fibrin clot that is your activated factor 13? So I hope our discussion about hemostasis is clear. So again, the ultimate purpose of this is to maintain the blood inside your blood vessel as fluid with no coagulation. If it is outside your blood already, it needs to coagulate. And of course, let's also not forget your fibrinolysis. Again, let me remind everybody to please read on pages 626 to 627, only the overview of hemostasis paragraph, okay. So with that, thank you so much for listening, everyone. So there is a second video right after this. We'll be talking about your mega-choreocytopoeages. So I'll see you on the next video. Thank you so much and have a great day.


a moment they'll remember for a long time. It's a rare privilege just to compete in a war game. It took incredible fortitude to get the job done tonight.


Good afternoon. Good morning in the United States and good evening in Asia. It's a great pleasure and honor to welcome the new Federal Chancellor of Germany, Olaf Scholz. Mr. Chancellor, you can imagine this great interest to listen to you at this traditional Davos agenda week. We're at the beginning of the year. We try to provide a state of the world message and also define the priorities for the months ahead in 2022. And you play a particularly important role this year, not only as the Federal Chancellor of Germany, but also as the Chairman of the G7 community. Mr. Chancellor, you have started your mandate with extremely ambitious, but in my opinion also realistic, transformation program. And I should add a necessary transformation program for Germany, mainly with the pillars of decarbonization with very ambitious objectives already for 2030. And also, of course, the digitalization of the German economy. As I mentioned, you have at the same time the responsibility for the G7 and you have started under, I would say, certain difficult circumstances. I refer, of course, to the political situation, particularly related to what we see now in Europe, in Ukraine, and also with the burden of moving Germany out of the COVID-19 crisis. So a lot to be discussed, Mr. Chancellor, the floor is yours. Professor Schwab, lieber Klaus, ladies and gentlemen, I'm sure most of us would have wished for a different start to this year. COVID has been with us for two whole years now and we are still struggling with the pandemic. Our digital meeting today is proof of that. So obviously I can't avoid mentioning COVID in my remarks, but I will try something that Germans are not particularly famous for, being optimistic. And combined with the inevitable dose of German caution, I hope to give you a realistic assessment of both the opportunities and the challenges that we are facing. And hopefully some ideas on how to deal with them. Working together, restoring trust. That is the motto you have chosen for this year's annual meeting, Klaus. And indeed, it is also a good starting point for our exchange today. So let me begin with working together. The last couple of weeks, my first weeks in my new office, have urgently reminded us just how important international cooperation, political exchange and dialogue are. Take the intensive talks we have been engaging in with Russia since the beginning of January. It is still too early to tell whether they will help de-escalate the situation Russia created by concentrating 100,000 troops along the border with Ukraine. But after years of rising tensions, staying silent is not a sensible option. That is why we are talking to Moscow in a range of different formats about our commitment to Ukraine's territorial integrity and about a key principle of our common European peace order that borders must not be moved by force, that right makes might and not the other way around. The Russian side is aware of our determination. I hope they also realize that the gains of cooperation outweigh the price of further confrontation. This is the basis on which we are engaging. Because we strongly believe that global public gods can only be preserved through international cooperation and peace is the most important one of them. Closely followed by global health. One of the most uplifting statements that I have heard during the pandemic came from the Israeli historian and author Yuval Harari and I quote the big advantage humans have over viruses is that we can cooperate in ways they can't and we do. European doctors are benefiting from the findings of the American, Israeli or African counterparts. Scientists from all over the planet are sharing their research on new variants and potential treatments globally often in real time. And two German researchers invented a vaccine based on the new mRNA technology that helped save millions of lives around the world. These examples are proof of the power of cooperation. They also illustrate the importance of exchanges like the one we are having here today. It was at Davos in 2000 that leaders launched the global vaccine alliance. Today, 21 years later, vaccines are by far our best tool to leave the pandemic behind us. Without a truly global immunization campaign, we will soon run out of letters in the Greek alphabet for new variants of the virus. But the good news is thanks to a far-sighted cooperation, we have the tools to break the cycle. And Germany already the second largest donor to the global vaccine campaign will continue to do its part. By supporting COVAX, we are determined to reach 70% of the world population by the middle of the year. And as part of our current G7 presidency, we will focus on improving the international health infrastructure, including in countries of the global south. However, we need partners to join hands, particularly in the private sector. So in the spirit of Davos, let us work together to fully fund the global vaccination campaign that would also be the booster shot our economies need. As we speak, those economies are facing the most fundamental transformation since the industrial revolution. For the last 250 years, our prosperity has depended on burning fossil fuels, coal, oil and gas. The effects of man-made climate change are felt by everyone in every corner of the world. That is why Europe has decided to become the first carbon neutral continent by 2050. Germany wants to reach that goal in 2045 already. This leaves us with less than 25 years to reach net zero, a monumental task. But a task that we can and will master. We will prove wrong those who are currently portraying our continent as a billiard ball in a great geoeconomical game between China and the United States. Europe offers the openness and liberal societies that benefit innovation. We are on course towards greater technological sovereignty, a top priority of the European Commission. And the global shift towards more sustainable growth will give Europe the first mover advantage. But of course, Europe alone won't end the climate crisis. That's where the light motif of working together applies again. We will use our presidency of the G7 to turn that group into the nucleus of an international climate club. What we want to achieve is a paradigm shift in international climate policy. We will no longer wait for the slowest and least ambitious. Instead, we will lead by example and we will turn climate action from a cost factor into a competitive advantage by agreeing on joint minimum standards. Ambitious, bold and cooperative, that will be the climate club's ABC. Ambitious by committing its members to the 1.5 degree target and to climate neutrality by 2050 at the latest. Bold by ensuring that we act now to reach those goals, for instance by pricing carbon and preventing carbon leakage. And cooperative by remaining open to all countries and by respecting WTO rules. We are not looking to be an exclusive club. By addressing technology transfer and climate financing, we hope to bring developing and emerging economies on board. Let me highlight one example of how this could work. Green hydrogen. Within the climate club we want to work on a common understanding of what green hydrogen is and we will coordinate our respective investments. That is the way towards a reliable global supply. The mutual benefits are obvious for a country like Germany with a strong industrial base and high energy demands and also for those who would become the main producers of green hydrogen, namely emerging economies and developing countries. Ladies and gentlemen, Germany is committed to playing a crucial role in the global transformation. We have set sail to turn the 2020s into a new beginning, a decade of transformation and progress for our country. By 2030, 80% of our energy will come from renewables twice as much as today. This requires massive investment in our infrastructure from electricity grids to hydrogen pipelines. We will speed up planning processes and stimulate private investment in future technologies and digitalization. And we will modernize our immigration laws to attract the skilled workers, scientists and technicians that our labor market needs. However, this transformation that we are now embarking on is not an end in itself. Progress is not an end in itself. And in hindsight, we sometimes have to realize that yesterday's ideas of progress can become today's and tomorrow's problems. Think about the ecological crisis. In the end, it is a product of former ideas of progress. So what we need is better progress. Progress that isn't measured just in its short-term results, but also factors in its long-term consequences and side effects. Progress that addresses the concerns of all of our citizens. Because we know that change in the democracy only works if it is by the people and for the people. This is precisely where the second part of today's theme comes in, restoring trust. The sheer magnitude and simultaneity of globalization, digitalization and climate adaptation leaves many citizens worrying. Will their well-paid jobs move away? Will energy prices or rents in big cities continue to soar? Will pensions remain secure and health systems reliable? Leaving questions like these unanswered erodes trust. Trust in our democratic systems and their promise of equal opportunities. And trust also in our social market economy and its promise of fairness. Yes, trust can erode, but it can also be won back. A recent global survey showed that during the pandemic, public confidence in science and scientific institutions has increased. And nearly 9 out of 10 Germans, an increase over 2021, set in opinion polls that they have trust in health workers. So where does that leave us governments and businesses? First, in an age of technology, our policies and decisions must be based on science, rationality and reason. That is why my government has established an independent board of experts and scientists who advise us during the pandemic. And when their credibility is attacked by a small but loud and radical minority, it is our duty to defend them. Second, citizens demand explanations for the changes our decisions are making to their lives. If we as political or economic leaders do not explain our decisions properly, people will look for explanations elsewhere. Politics is Will, the great Swedish Prime Minister Olof Pymer once said. Will and communication, one must add in today's digital world. And finally, we must not allow technological innovation and growth to be decoupled from social progress. On the contrary, only a society of mutual respect will stay united through the apocal changes that lie ahead. Social justice and equal opportunities do not stand in the way of transformation. They are necessary preconditions that make transformation work. I know that many of you share this view and that for me is another source of optimism. Ladies and gentlemen, my hope is that we can maintain and build on that unity. Some will try to tell us that dialogue and compromise are signs of weakness. Some will try to pitch climate action against prosperity. Some will argue that social progress hampers economic growth. And some will try to divide us into cosmopolitan and regular citizens anywhere and somewhere rich and poor. But the truth is the progress we want, better progress, will only be possible if we overcome these divisions. Working together is the way restoring trust is our goal. Thank you for your attention. Thank you very much, Federal Chancellor. Very ambitious, very comprehensive, but as I mentioned, very necessary program because we are living in the age of the forced industrial revolution. We have the chance for a new renaissance if we use all those capabilities in a very responsible way. Now you mentioned many priorities which you have for your government and you put particular emphasis on the world trust. If I may add one question here, trust depends also very much from a macroeconomic stable country. How do you see macroeconomic stability in this context of what you just outlined? I see that macroeconomic stability is key for the trust into the future and this is why we have to work on our goals and all the aspects have to be followed which are important for this task. So first, we will do a lot for growth and second, we understand that this growth will only be successful and we will be going into the right direction if we understand that digitalization and fighting against climate change are important for the future. And so these are the most important aspects of our decisions we will have to take and this is why one of the first activities of the new government in Germany is to make all processes that fast and that successful that we will be able to reach our aims and our goals and this I think is the basis for a good stability in the economic development and for growth. I would agree and I would also coincide with your view that digitalization cannot be just referred to in the context of industry. It has to be public administration, it has to be the public in general, our schools and so on. If I may have another question, Mr. Chancellor, you didn't refer in your speech specifically to Europe. You made some remarks related to Europe but Germany is the strongest power inside the economic power inside the European Union. How do you want to contribute during the next four or even longer years to a stronger unification of Europe? We are working very hard for getting a better Europe, a better Union to say it like this and this is absolutely important. The world we will live in in the midst of the century will see 10 billion people living there and knowing this it is absolutely important that we cooperate within the European Union and that we are working on the necessary success. So this is one of the key tasks of the government to make Europe stronger. That this is something that could work. We saw and see during this crisis we are living in now fighting against the COVID-19 pandemic and its economic and social consequences. The European recovery program is a sign of what we can do and it should be also the idea how we could manage to solve our problems in future. If we cooperate in the different fields, may it be defence, may it be foreign policy, may it be the fight against climate change and so working on European sovereignty and cooperation is one of the key aspects of our politics. Chancellor, thank you. I would like to come back to your presidency of the G7 and you must have already an agenda I know and as you explained decarbonisation plays a big role but I think also you foresee and you mentioned it very much how the G7 could help the developing world to catch up and to have some means at its disposal to deliver its part in order to achieve as in Paris accord or even to do better. Could you share with us some of the specific ideas you have for the G7? We are very happy that we are now able to do our task in the G7 with the presidency and there are a lot of questions that are to be solved in the international community and where the G7 can play an important role. One I already mentioned it is to fight against climate change this is a global task which could not be solved just by one country so we have to cooperate but if we follow this path if we do the necessary decisions in our countries this will have impacts on our industries and our businesses so there are a lot of debates about how we can give them a certain way of support to exist and survive in a global environment that is not in any case following the same direction so the idea for getting a global cooperation within this field is this climate club I already mentioned to have a cooperation and it's open it is not closed it's open especially to the global south to the big countries in Asia that are working to follow the same goals and so I think this is one of the main topics to be discussed the second is how we can fight against the economic consequences of the crisis and especially the poorest countries and those that need support in this development development growth will be only successful and sustainable if it is something that is happening to all countries and the people all over the world so this is the second big question and obviously also the question of the global health is of importance we have to do something that it is feasible for all countries to resonate their people and so we are working very hard to make this happen Mr. Federal Chancellor, I like very much the metaphor ABC, ambitious, bold and collaborative and I was already thinking when you are mentioning it so we should use it as a theme for the annual meeting 2023 next January but I would like to come back, you mentioned that the World Economic Forum in Davos we were at the origin of cooperation related to vaccines as you know Mr. Chancellor Davos of the Forum was also at the origin of GAVI and JPEG two organizations which play a major role I know that already at the G7 and G20 last year a public initiative, a comprehensive initiative was discussed how we can deal with such risks in the future, health risks, not just related to COVID how can we prepare the world to be much more resilient so we are not unprepared or so much unprepared even new pandemic would hit the world do you have any objectives in this respect? First it is necessary to do what I already mentioned in my speech and in an earlier answer we have to make it feasible that all people in the world have a chance to be vaccinated and so I really ask all those who are able to to support the COVAX initiative and give their financial support that is necessary that we can buy the vaccines for bringing them to all those who need them and this is also that we will do our best job to make it happen that those companies successful in this field could build new plans possibly somewhere in other countries of the world and also in the global south that they could produce the vaccines for their people so this is what we are working on and then we need scientific cooperation because this is the lucky aspect of this very severe crisis that we learn that science brings us out of the situation so we have to organize global cooperation in research and development of new vaccines and health infrastructures that are good for the people all over this globe Mr. Federal Chancellor we are coming to the end of our time you know the world they could inform of course we are known for Davos but we have 50 different platforms for public private cooperation in the environmental area related to skills which are needed related to innovation and I could go on and on so maybe one last comment how can business in general you mentioned already innovation how can business in general be of support for your program what would you expect from business not only from the German business community but from the international business community to contribute to your objectives there are a lot of tasks I think would say research, investment and social cohesion are key so let the people share from the success you get from your investments and so this investment should be guided by what we call the stakeholder mentality or stakeholder capitalism and you mentioned it in your speech it should be human centered it should take care of people and it should also take care of our planet thank you very much Mr. Federal Chancellor and I hope to see you in person hopefully in the next who knows when in Davos and all our best wishes for your program which really is pioneering but we need to achieve the Paris objectives we need to reduce inequalities in the world we need to make full advantage of the force industrial revolution and I think you are on a good way to do so so thank you and congratulations


All right, good afternoon cyber traders welcome on back here this Thursday July 6th shortly after 2 30 p.m Eastern great to still see Michael. Well, we got two Michaels. We got Michael D. Michael B. We got John with us here We got Andre. We got Jeff. We got Donald just before I saw a later lurking around just a moment ago Kathleen Tim Ronnie etc great to see all our students and members alike right now and great to have you joining us back as Well on social media if you're joining us on Facebook live LinkedIn Twitter YouTube the works folks Let's hop right into it as we always do the markets have made a full recovery back up from the morning Took a little bit after that 10 30 reversal time much like Fausto always talks about with the cyber clock So it's saying that you know, hey for as much as the markets dropped today Perhaps we could see a nice bounce around that time But you're not necessarily expecting to see a full retracement back up and then some so no Hopefully be having even stronger clothes as we did just the late morning early afternoon AI right here It's basically break even right now from yesterday's clothes price Very strong push up the 40 once again retesting that level. We love that word retest Well, if anything, it's actually retesting the closing price from yesterday not just that 40 level So, you know what we're gonna put this on our watchlist to begin You know, it's not up or down a whole lot percentage wise But I mean obviously it's made a big move in terms of you know points across the day and you're looking very Strong right now. So if anything the the bigger price to focus on though is not 40. It's not 40. It's 40 12 It's a 241 thousand share block print got filled yesterday right at the market close So that's pretty big. You got a big iceberg here for about 45,000 at $40 26 cents There is a little bit of resistance here before this looks to try and really pop and run higher But strong enough right now. We'll definitely start off at this AI trade All right, I'll tell you what I didn't clear all my wacky lines in my chart here before this meeting So we'll probably run into Mara M. A. R. A. At some point probably a couple other stocks I charted briefly, but uh, just wanted to check out Rivian while we're at it here, too Our IVN was very strong heading into the mid-morning ended up balancing a little bit earlier than the S&P did and the rest of The other stocks that we've been following so right around 1030 ended up making a beautiful balance pushed up towards 21 and change It's looking pretty similar right good strength We're not going to put every stock that's moving with the market on our afternoon list here But you know what hey yesterday afternoon at this time It was just beginning to bounce and I was not a believer and it led to a big bounce So that was a slight miss from our part there But with that hey, there's always room for more if not today it could be tomorrow could always be next week This stock Rivian it's not going anywhere. You know basically in the sense of we're gonna keep trading this thing It's gonna be a sideless stock for a long time from now And right now I'll still put this on our main watch list here, right? Looks pretty strong up a little bit more than AI AI just blasted right through that iceberg order at 40 26 Look at the prints fall on the tape right there actually purple well that actually could be pretty good should that hold This support momentarily so very good start for AI good start for Rivian right now our IVN Let's just go from top to bottom now otherwise We got a stock here. This has to be a glitch has to be a glitch from trade station for right now ELVA up 746 percent Could be some sort of stock split thing there a little glitch from trade station scanning and I think that's the case but uh Yeah, not really doing much right now. This ELVA trade will pass on that now caribou CRBU this was a phenomenal push from pre-market really nice run from pre-market early on I was on a coaching call. It's one of our students earlier. We were not a believer of the initial pop We weren't a believer at from 480 We actually missed an entry because we were a little too reluctant We isn't me and then from there once it blasted above five we took the entry at 505 Even at that point though left a lot of money on the table and that's for damn sure this thing ended up running up over 550 from their pop much higher and from that stage a bunch of us were able to jump in on that trade or jump back in So overall from head to toe CRBU has been a really good really great trade today But though we've never really followed this stock Really much before so prior to today the stock just on average trading less than a million shares on average a day You know right now it kind of resembles just a pop and drop stock one of those false breakouts And it ends up making a head fake and it dumps right back down if you look at the daily chart here It kind of speaks for itself Yep. All right, so CRBU done for right now I'm writing down for tomorrow or maybe Monday next week just sideless stock maybe for the next couple days And keep it going EDTX not doing much right now. We'll pass MULN. We're familiar with this stock It's been a former runner for us over the last year or two. It probably has been reverse split non-stop since but uh Yeah, this thing cheapy stock ended up making a pre-market pop, but that's all there was to it there Keep it going BNED Barnes and Noble. Oh shoot. No, that's funny. I didn't realize the company there. Oh, that's great BNED nice little pop right now for any of our bookworms out there This could be a fun stock for you this afternoon good liquidity good volume on the day You got about 15,000 shares on the offer right now at 215 That had to have came in over the last three or four or five minutes here after it popped and dropped from that price But yeah Barnes and Noble interesting nice You know what I think we got a little time here a little amount of time I got my Benzinga Pro up right here And why not just check the news just to see why it's up. I'm curious It's not gonna determine where and when I jump in if I jump in but definitely for right now we're gonna put it on our watch list and Lo and behold There's no news There's no news on the stock folks that I see there's nothing back from June 13th It just says retail apparel stocks trading higher off the CPI Benzinga is usually on top their game. So this might just be some sort of you know pump off of no news Maybe there's news to come who knows we'll find out more in a moment either way It still looks good as a day trade for for us here G E N I genius genius sports Nice trend right now and from the morning is grinding on up. So, you know, definitely we're gonna put this on our watch list to it looks better than the be any D trade even and Yeah, Genie Now we'll kind of just skim through here. I mean if there's anything moving with the market It's not gonna be up as much as you know those, you know that 10 20 30 percent. I saw a rich coal add DOCN earlier This was a hell of a run digital ocean ended up making a big squeeze from basically like 40 up to 45 It's filling in sideways here hasn't truly broken lower so I could put it on our main list a little expensive for us mainly but You know if you want to do calls on it and hopefully it has good Volume on the options side of it, but uh, that's one thought otherwise just trade smaller share size Spread isn't really ungodly right now Meaning it's like, you know a little wide here and there, but it's not like 20 cents not 15 cents 20 cents That's for sure All right, I'll slip this on the bottom here if anything DOCN Children's place little pop earlier today and hey with the drop-off we had earlier this morning UVXY and verse ETF This killed it earlier today, but obviously now that the markets have pulled back. This isn't gonna be a great one now at this point All right Let's see if there's anything else like kind of up that 5% Rivian. Obviously we talked about before already on our watch list Quadruple see I saw a couple of our students call out earlier today. It was a nice move Broke higher from yesterday's high And still kind of holding strong here, right? It is still kind of holding strong Good volume on the book Kind of selling myself on to it folks. So you know what for right now? This quadruple C makes the cut we'll come back to it at the end if it dumps off will scrap it But for now it looks decent writing a little too slow right now for us right there All right, so folks if there's anything else looking good on the way up type it in on the chat board Let me know right now. Otherwise, we'll hop over to the loser's side here Sam asking what was news on Benzinga on GE and I I'll take a look at that in just a moment Sam. Oh X X II it's actually not too close to the ground floor being zero and it is easy to borrow This thing's been falling falling off a cliff lately too. So is this all-time lows? Looks pretty darn close to me 225 is the all-time low it looks like back from Late 2012 Right there in November That was about 50 cents to go but obviously, you know, definitely had some big support right now if anything It broke under big support roughly around a four bucks It did that just overnight into the morning. So yeah nice move on the way down here for X X II I don't mind slipping this on the back end to Got overstocked down big little flat right now, but it is at the lows Right and got to respect that part. If it had better liquidity, I'd be more sold on it I got a lot of stocks down percentage wise right now TWU Peloton take a look at those trades at least just to see what they look like Nothing really too jumpy out there to me folks nothing really standing out too much on the loser's side and typically as I say that I'll jinx myself and though there will be a stock that looks incredible I was hoping it was gonna be a firm here, but not really the case Jobby hey, it could be jobby jobby down 13 percent. It's at the lows It is a gaffel to just based off of last week's run up and with that. Yeah There we go. I forced the jinx, but we got it From Bill on genius there you go Bill appreciate that my friends. I'm helping him stand out there with the news and If all partnership looks like or extension play to ask him. What's up with ROIV? Good question and definitely Nice pop. It's got to be halted Take a look Roving sciences, this is from June 29th Not even today and it doesn't even show the halts either So one thing I will do on top just give me a quick second here a quick little lesson in terms of halts We talk about this mainly throughout the fees two and three curriculums that we offer Especially when you're trading live with Fausto in the advanced class, you know If there's a halt that he's in he'll oftentimes just pull this website up here Nasdaq trader calm check the halts. So yeah, this is a halt Resumption time. Well, this is from earlier. So this is a previous halt Volatility halt right there it shows doesn't show anything else on top though, whether it's news related on top or not, but Good shot for right now Lita. Yeah ROIV. We'll just see what's up with it If you pop and drop them, we'll just scrap it, but otherwise right now looks decent. Oh There we go live reopen. Boom. Perfect. All right. What's the opening halt print? What do we got right here? Probably gonna beat me to it 1150 252,000 share print filled at 1150. How can you tell? Well few ways time and sales number one Number two book map level four. That's always a great way to tell and then finally actually from the trade station matrix That guy right there So definitely filling the gap right now. We'll keep it on our watch list in terms of the volatility It has decent volume for right now in the book Hopefully more eyeballs catch on to this trade and we could even see the spread fill in that much more 1150 is a huge level though. That's for sure All right, so folks last call. Let me know if there's anything else up down left right more than 5% Anything that looks good chart goes from left to right stocks go up and down Let me know if there's anything else looking good that you see Got a good list don't really need to force anything else out out there But so far we got two four six eight nine different stocks to work with This looks like a dump off. That's for sure. We're gonna keep it on our watch list again It's a volatile stock. We embrace the volatility. I don't expect it to pop higher now at this point But we'll see if it ends up making like a nice range or if it ends up actually breaking lower Actually would be a decent short opportunity there. So it's back down to the gap Latest is oops again later. It's all your fault Teasing her obviously. All right. Let's see if there's anything else folks Just kind of look at the site or look at the rest of the stocks from our main list The BNED it's still holding GNI still holding XXII was the short that we had what was the one that we said we were gonna scrap if anything the quadruple C right Dipped off a couple pennies but still looking decent hasn't broken lower just yet And we'll keep it on there All right folks, we're gonna wrap up for right now rich will be on the mic taking you into the close He'll be on a three o'clock, but hey just like I had said yesterday We had missed a small bounce a couple of us at least did some of us were there for it on Rivian But I would suggest to start and stick to this watch list Hey, just getting them a whole market for the last 14 whole minutes So of course there could be one or two things that make a subtle move here or there But hey, if we didn't call it out now folks I'd rather is just focus on what we got AI rivion those two alone. You should have your hands, you know full Right, and then just the others like the ROI V that that's definitely a nice volatile stock to keep your eyes on So start and stick with this list then you know from there at that point rich will be on a three o'clock Then we'll see what's out there from that stage folks. It says thanks. Josh for not kicking me out later Never come on now now folks.

Talk to you soon


Hi, I'm Zor. Welcome to Unisor Education. Today I would like to solve a little bit more difficult problems, just a little bit, related to the superposition of the forces. It's the series of the problems called Problems 2. It's part of the Physics 14s on Unisor.com. That's the website where this course is presented. On the same side, there is a prerequisite course which is called Math Proteins, which is relatively comprehensive course of mathematics for high school level students. And I do recommend you to watch this lecture and every other lecture actually from Unisor.com rather than from YouTube or any other source, because every lecture on the Unisor.com has very detailed notes. It has exams for those who would like to take them. And it also has certain educational functionality if you would like to study under the supervision of the parent or a teacher or a flipped classroom or something. Okay, so the problems. Problem number one, you have an incline, a slope with a block on the top. Well, this is basically a pulley. There is a little wheel which basically rotating without friction obviously. Now here we have one point object with mass M1. Then there is a thread around the pulley. It goes down and this is M2. So this is the vertical line. This is an incline and there is an angle, let's say alpha. Now, what's interesting is that, well, let's just consider that M2 is greater than M1, which means that my thread moving this way down. Now obviously it's all happening on Earth, so the weight is equal to mass times acceleration of the free falling, which is 9.8 meters per second square. Alright, so what's interesting is that as my combination of these two masses is moving around the pulley, it exerts certain pressure on the pulley. I need to know the value of this pressure. Well, let's just think about it from this way. First we have to analyze the forces which are acting. Now obviously we have the weight. Also, since this is an incline, there is a pressure which this object exerts on the incline and the reaction force back. So these are two forces, the weight, and there is a reaction force. Is that it? Obviously not, because these two forces are the only forces which are acting. Obviously the mass will go downhill. It goes uphill because there is a tension, which is the result of this guy going down and it pulls the thread. The thread we are considering to be non-stretchable, so there is no friction, no stretching. So there is a tension on this particular thread which basically pulls this particular object upwards. And obviously there should be the balance here. So this is the resultant of these two forces. This is R1, this is W1, this is weight, this is reaction from the incline. And their resultant is this way. And obviously the tension should go along the same line, along the thread basically, because our object is moving that way. Right? Now, what kind of forces are acting on this guy? Again, it's weight, W2, and again the tension. Tension just slows it down. Basically it still goes up, but the tension slows it down. Now, so what we have right now is these tension forces, they are the same because it's the same thread, right? And their resultant, one is going this way, another is going that way. So the resultant would be going upwards. Now, obviously there should be some kind of a force, which is the pressure which the thread exhorts on the pulling on the support mechanism here, which basically keeps the pulley intact, right? So the combination of these two forces and this pulley is zero, and that's why we have this pulley standing basically on the same place without moving. And this is the pressure which we would like actually to find out. Well, obviously it's supposed to be related to these two forces, the tensions, right? So unless we find the tension, we cannot find the pressure on the pulley. Alright, so let's start with the tension. What can we say about this particular problem? Well, now this is angle alpha, so this is angle alpha, right? Because it's too perpendicular to these two, which means we can define this force. Let's call it F1, because it's the first object, right? So F1 is equal to the W1 times sine of alpha, or M1g sine of alpha. Okay, got that. Now, what can we say about moving of these two things? The linear moving along this incline or this downward, these movements are supposed to have certain acceleration which is exactly the same, because they are connected by the same thread. So this going this way and this going this way, they're supposed to be movements with exactly the same acceleration, speed and acceleration. So what's the acceleration using the second law of Newton of this guy? Well, acceleration, let's call it A, it's equal to T minus F1, right? Because T goes along the movement and F1 goes against the movement and that should be divided by M1, the mass. So that's the acceleration of this guy. Now this guy has acceleration of also the same A. It would be W2 down along minus T goes up prevents divided by M2. They should be equal to each other and that's how we will resolve it for T, right? So let's write it down here. C minus F1, well I can actually substitute instead of F1, I can substitute the whole value. M1g sin A divided by M1 equals 2. W2 is M2g minus T divided by M2. So we have to resolve it for T and that's our first step to find out the pressure.  Am I right? Hope I'm right. Okay, so we found T. Now how can I find the pressure if I have the T? Well, basically if you have these two forces, let's call it T, this is from this one so it's T2 and this is from T1. These are continuation of these but they are the same actually so I don't have to really have an index since it's all the same thread. So I have this particular story. This is T, this is T. Now what's the angle between them? This angle is, this is the right triangle so it's the same as this one which is pi over 2 minus alpha, right? And I have to find a force which is basically equivalent to them which means it should be on the bisector, right? So the combination of these two is, well I can find this piece, this is the rhombus by the way, right? Because these two are the same and it's parallelogram. So I have half of this angle which is pi over 4 minus alpha divided by 2. I know this T so I can find this one, it's this times cosine. So it's T times cosine of pi over 4 minus, that's the half and if I multiply by 2 it will be the whole line, right? Because I found only the half of it. From this times cosine of this angle it's half of the resultant. Okay, so that's the answer and it corresponds to whatever I just said. Because right now I can say that this is equal to T is this divided by this sum so it's m1, m2, g1 plus sin alpha divided by m1 plus m2. This one and times cosine of pi over 4 minus alpha over 2. That's the answer. So that's the pressure which is applied by the whole system of these objects and pulley and all this. The pressure applied on the base of the pulley basically. I scratched my m. Okay, next. Next is you have an object on the thread. I have an angle 5 and the length of the thread. And now this object I'm basically launching to do the circular movement. So it goes this way. So in the horizontal plane this thing is making a circular trajectory. Now what do I have to find out? I have to find out if I have some time T I would like to find number of rotations per time T. Okay, now again let's see what kind of forces are acting. Obviously this is the force which is w1. Well w actually have only one object which is mg. And I have obviously a tension here. And also I had a force which initial push around the circle. It's no longer participating basically in other movement. So as long as my speed is constant it just continues indefinitely circulating considering there is no friction etc. So this force which is along the trajectory which was in the very beginning to basically start the movement is no longer participating because it's no longer applied. It was just initial push and that's it. So there is no such force anymore. There are only two forces down and along the thread, the tension. Now but since my object is moving in a circle obviously there supposed to be some kind of force which keeps it on the circle. And obviously this is the force which is the combination of these two. So this is the resultant force and this is the centripetal force which keeps it on the orbit. Now we know that the force is equal to mass, linear speed divided by r or mass r omega divided, multiplied by r omega square. So this is angular speed, this is linear speed. Well let's concentrate on this one. So this is the force which is the resultant of these two forces. Now if this is phi, this is phi and this is phi. Now the weight I know, well I don't know the mass but I probably don't need it. So how can I find this one? Well if this divided by this is equal to tangent, so it's the weight multiplied by tangent equals to my force, let's call it f, which keeps it tangent of what? Tangent of phi. This is the force which keeps it on the trajectory which is supposed to be this one. Oh by the way I didn't know the r, r obviously is calculated from l.  So and the weight is equal to mg, so I can put mg here. Now what we have from here is basically all we need is omega because this angular speed will obviously allow us to define how many rotations per unit of time we have. So we obviously can cancel t, I will have g is equal to l times sine of phi times omega square. So omega is equal to square root of g divided by l sine of phi. Okay we've got omega. So this is angular speed which is number of radians per, let's say second, right? Number of radians per second. What we need is number of full rotations per time t. Well if this is number of radians per second then within the time period t we will make number of radians would be obviously t times greater which is t times square root of g over l sine phi. So that's number of radians. Now if you would like to change it to a number of rotations and each rotation is 2 pi radians I have to divide it by 2 pi. And this is my answer. This is number of rotations per unit of time t, rather per t units of time. Say correctly. During the time t. Okay, next. Next is the following. So you have a wedge. This is phi and this is phi. Wage is going down. Now here are two similar masses, point masses, point objects obviously m and m. Now the wedge has mass m. Now it's all on the table. There is no friction. So as wedge goes down it pushes aside both objects, right? Now my task is to find out the acceleration. These two objects will be pushed aside, right? All right, so again what we start with obviously the forces. Now what kind of forces actually are involved here? Well, the weight here and weight here are insignificant because they are completely balanced by the reaction of the table. So that's not important. So what is important is, let me just scratch this. So we know that this is angle phi and phi. What is important is the reaction from this particular movement. So it's always perpendicular. Now these are point objects, right? So the reaction will be perpendicular to the sides of the wedge. Let's call it n. n here and n there. So the wedge goes down and it pushes with certain force our blocks aside. And the blocks, these two blocks are reacting by these forces back to the wedge. Now the wedge goes down, let's say with acceleration a w. And these two are going left and right correspondingly with acceleration a. Now how can I transform these forces into the forces which are acting along the direction of the movement? Now direction of the movement of the wedge is down, direction of the movement of these is horizontal, left and right. So I have to convert all the forces into the forces which are parallel to these two directions. Now in case of the wedge, I have the weight, it goes down and it's equal to mg, right? And I have the force which is perpendicular to this one and perpendicular to this one. Now I would like to convert this force into horizontal and vertical components. Now horizontally they will act against each other because they will act along this line here and here. Vertically they will go up here and up here. So I would like to find out these two because they are acting opposite to my weight, right? So let me just do a bigger picture and you will see, okay, this is my force and I need to know the vertical component and horizontal component. So this is my vertical component. Now this is angle phi. So this is angle phi, right? Because this is perpendicular to this and this is perpendicular to this. So if I have this which is n, unknown obviously, then the vertical is equal to n times sine of phi. And I have from another side exactly the same thing. So they are both acting that way and they are acting with a minus sign because they are going directed upwards and the weight goes down. So mg. That's my total force acting vertically on this particular guy. And that's why the acceleration is equal to this. This is my acceleration AW. Now let's talk about this guy. Now this is the same n by absolute weight, just differently directed. Now I need to know its horizontal component. So again let me just do it a little bit bigger. This is my n. This is my big block. I need this component, this one. So now this is perpendicular to this and this one is perpendicular to this. So this is phi. So it's n times cosine, okay? So my object has n times cosine phi as the force and divided by m is acceleration. That's different acceleration obviously. Now how many unknowns we have? m is unknown, a is unknown, AW is unknown. So we have three unknowns with only two equations. Not good, right? But let's consider it this way. What if you have this wedge and in the beginning the point where it actually touches of this block is here in the very corner. Then the wedge goes down and this thing is sliding to the right. As the wedge goes all the way down, this thing will move to the right by this piece, right? So whenever wedge goes by this piece down, my block will be moved to the right by this piece. So their ratio is actually the ratio of the displacement and ratio of the velocity and the ratio of accelerations obviously because they're all proportional. So if the movement down is proportional to the movement to the right, then acceleration will be also proportional. So that's how I can establish my third one. So how do they are related? If this is phi, right? Then this is acceleration w would be to acceleration, no, sorry. This will be acceleration and this will be acceleration w. This is tangent of phi, right? Now these are three linear equations with three different unknowns and we need to know the a, which is actually very easy because again these are linear equations. And the result is in my notes and I can give you the result here. A is equal to G tangent phi divided by 1 plus 2 m over m times tangent square phi. So this is basically easy exercise on system of linear equations. From here you get n, you substitute n into this and you will have only a and a w. And then from this you can get a w and substitute the result and that would be the solution. Very easy. So I'm skipping all these technicalities there through them. Notes to this lecture have a little bit more details of this trivial calculations. We don't want to stick on it. And the last problem is the following. Let's imagine the person who would like to make a long jump. And it's not exactly the way how long jump is made but this is a good kind of a physical problem which is related to this. So let's consider him accelerating to a certain speed. At this point he jumps up. So what happens? Well while he is jumping up and then falls down he continues this horizontal speed and that would be the lengths where he lands. So my purpose is to find out the lengths if I know that he was accelerating during time t with acceleration 0 from 0 to some kind of a v, some kind of a speed. And then he jumps up and I know the height. So by knowing the height and these parameters the time and acceleration I would like to find out how long he will jump. Well look at it this way. First of all let's find out the v is equal to a t. During the time t with acceleration a from velocity equal to 0 that's my maximum velocity. And this is the velocity or speed actually because it's one dimensional as he would fly forward during his jump up, right? Now so all we need to know if we know the horizontal speed we have to know the time during which it happens. So the time is as he jumps up I know the h. So from h I have to find the time. Well that's actually easy because if he goes up first it means he is pushing himself with certain vertical velocity, right? And then during the time it goes up let's say it's time t vertical, no it's better to say t up. What is his parameters? As he goes up he has a negative acceleration of the free falling which is g and at the very top his velocity is 0, right? So if I will subtract from the initial speed as he goes up this I will have 0, right? That was initial speed. At the end of the time period speed is 0 so basically that's what it is. So v vertical is equal to g times t up. Now how about going down?  So the h would be equal to gt, sorry, yes, acceleration and speed divided by 2, right? That's the formula because the initial speed is equal to 0. It's only horizontal so vertical speed is 0 so this is my going down. So this is down. Now considering my time to go up, time to go up should be equal to time to go down, right? So basically if I am calculating only this or I can actually prove it I guess because the same h is equal to v vertical times t up minus gt up squared divided by 2 minus because g is slowing me down, right? This is my initial speed up times the time. That's my formula for uniform acceleration and acceleration is equal to g, right? So that's basically two things where I can find out my t up and t down. They are supposed to be equal and from this we can say that v is equal to gt up, right? And because v is the beginning speed, 0 is the end of the speed. So v vertical minus gt up should be equal to 0 from which we derive this which means that in this particular case we have h is equal to gt squared gt times t minus gt squared this is up divided by 2 which is gt squared up divided by 2. As you see it's exactly the same as t down, right? So that's the proof basically that whatever the time you need to go up is exactly the same the time to go down. And from here obviously you can find time if you know the h. Time is t up plus t down but they are exactly the same so you can double the time up. So the time of the entire up and down would be equal to 2 times 2h divided by g square root. 2h divided by g. So my time is known. My speed, horizontal speed is known. So their product which is 2at square root of 2h divided by g is the length of the long jump. That's it. So what you have to do now and I strongly recommend you to do it. Go to the website, go to this particular problems number two in superposition of the forces. This is how you go.  From mechanics you go to superposition of forces and there you have the problems two lecture. Now the nodes contain all these problems and answers so do it yourself. Try to solve all these problems, check against the answers and that would be great exercise if you can do everything just by yourself. Alright that's it. Thank you very much and good luck.


Tiktok changed our lives and business. We're on track to do a million dollars in our first year in sales and 90% of our sales are from Tiktok. $900,000. I should also say, I was at it for a month and I told my husband, I'm over Tiktok. There is no possible way this is going to translate to sales. It's a horrible shopping experience intentionally by Tiktok. There's a reason brands aren't doing this. That night, our first video went viral. We completely sold out and we have sold out consecutively in today's environment. Social media can literally change. In your case, your life from a side hustle to a full-time job, to a full-time business, to employees.
