Hey everybody, this is Brett with Summit Auto in Fond du Lac, Wisconsin. You're new and used Ram and light duty truck headquarters. And today I'm excited to show you this brand new 2021 Ram 1500 crew cab 5 foot 7 inch short box with the Ram box. This is a Laramie level B package and it has the night edition on it as well. This is granite crystal is the color PAU is pink code. It has the 5.7 liter V8 Hemi motor, which pumps out 395 horsepower, 410 foot pounds of torque. You're going to get 21 miles per gallon on the highway, 15 city for an average of 17. Now this is the one without the e-torque. So you don't have to worry about that electric motor or anything in the start stop. What we're going to do is we're going to walk around. I'm going to show you exactly what's going on with the night edition. The Laramie level B group and then we'll get inside and check out the ins and outs of the vehicle. But first I'm going to show you the original window stickers. So give me one second. Here's the original window sticker. You can see 2021 Ram 1500 crew cab Laramie has the 5.7 with the MDS, which is the multiple displacement system, which turns off four of the cylinders on the highway has a eight speed automatic transmission. Nothing on your left is your standard equipment including the backup camera, the 321 gears, the receiver hitch, interior features, the A4 Apple CarPlay, Google Android Auto, nine amp-fied speakers with subwoofer.

Night edition is $34.95.  You get the 22 inch all season tires. You also get anti-spin rear differential with the night edition, kind of a little weird side note with that. It's always on the half tons. Black interior accents, full length upgraded floor console support performance hood and the wireless charge pad. Now on the Laramie's they don't have level one or level two anymore. They have level A and level B. So this is a Laramie level B equipment group, or if you kind of think of it like a Laramie level, or a Bighorn level two. So it's the upgraded Laramie package, $37.95 is the charge for that. You get the 4G LTE Wi-Fi hotspot, 19 speaker Harman card and premium sound automatic high beams, heated second row seats, park sense, rain-sensitive windshield wiper storage on the rear seats, power tailgate release, 6040 split folding slash reclining seat.

Dual pane panoramic sunroof is $14.95, rear wheelhouse liners are $195.33 gallon fuel tank. This one has the Uconnect 12 inch display with navigation which is a $13.95 option and that gives you serious XM with 360 L. Ram box is $995 and then the trailer brake controller is $295. Total MSRP is $66.5, $25.

Three year 36 bumper to bumper, five year 60 powertrain. Here is your fuel economy, 21 Highway 15 city average of $17 and then the safety ratings on the Rams are just ridiculous, five and four stars up and down the board and just a very safe vehicle to transport anybody in. So I'm going to go around show you everything with the night edition, we'll hop up front right away. So the first thing that you'll notice with the night edition is that you get the painted front bumpers, you also get the gloss black grille, the blacked out Ram logos, you also get this gloss black trim around the right under the hood there. Now notice you also get the blacked out headlamp bezels. This has the LED headlamps, LED running lights and LED fog lamps, we're going to turn those on towards the end of the video here and do a walk around with all those lights on. Black 1500 and Hemi logo, you also get the black Ram logo on the side. Of course those 22 inch painted alloy rims are part of the night edition and those always come with the Goodyear Eagle Touring 28545 R22s. Now those are all season tires but kind of like a highway tread pattern to them. You get the painted black step bars which I think look really good with this truck. All the Laramie's come with the fender flares and as we come to the back here you'll notice that it has the painted rear bumper. Also you get these kind of black chrome exhaust tips that's also part of the night edition. You get the blacked out Laramie logo, Ram and 4x4 logo as well. Of course it comes with the towing package, receiver hitch, 4 pin and 7 pin wiring and you get the LED tail lamps in back as well. Ram box, kind of a neat feature. These pop open like so and they lock with the ignition key so when you lock the doors it will lock with this as well. I was like showing this side because this side has a 115 volt 400 watt plug in right there as well. And you can turn on the LED lights inside the Ram box with this button right there. This one also has the four corner air suspension on it and let's hop inside the truck and take a look. Inside the Laramie level B package gives you the black leather and suede interior. These are heated and cooled front seats. Notice you get the suede on the backrest too, the nice soft touch leather. Up there you get Laramie stitched into the backrest. You get the gray piping on there. Both these front seats are power with lumbar. You get the Berber floor mats in here as well. Go headlamps, power pedals, tilt and telescopic steering wheel. Power windows, power locks, power mirrors, these mirrors do fold in which is a really nice feature. There they go. And both sides go so that's nice especially on the passenger side. On the doors here you get the suede trim with the black inserts. Everything's leather wrapped as well. We'll hop inside and turn the ignition on. You can check out the instrument cluster, the radio and everything inside here. So you notice you get the compass, outside temp, digital speedometer. You get your battery voltage, you also have oil temperature and you can change those corners to read pretty much anything you want. The 7-inch LCD display, it's all configurable, you can go through all your different stuff here. Screen setup, messages, all that good stuff. So really a very nice setup there. You get the heated leather wrapped steering wheel, cruise controls and gear selector on the right Bluetooth and information center controls on the left. Audio controls on the back of the steering wheel has the push button start, 8-speed automatic transmission, your push button 4-wheel drive and then you also have your 12-inch Uconnect 4C radio. So AM, FM and Sirius XM radio capabilities on this radio as you can see here right now we're on XM. And then of course it does have the factory navigation system and you don't have to pay a subscription or anything for that. That just comes with this particular radio. You have the heated and cooled C-buttons, you also have your backup camera which I love the backup cameras on the Rams, they're HD, super crystal clear. You have this zoom in so you can zoom in and get hooked up to your boat camper or trailer the first time every time by yourself, really convenient there. And you have all your different climate controls that you can do through here so you can do the climate controls on here or you can do them on the side of the radio with all the more tactile buttons. You have all your different apps in here including travel link, more heated and cooled C-buttons, your backup camera, auto dimming mirror, app manager, Sirius media, climate, it's basically some quick links to whatever you may want to get to, SOS, assist, all that stuff. Then it does have projection manager where you can project your cell phone through Android Auto or Apple CarPlay to the screen. You can play music through there. If you have a different navigation system you can use that through the radio. We actually did a demo on Android Auto on an 8.4 you connect 4C radio so this is just like it except bigger so that would work there. So check that video, it's in the upper right hand part of the screen. Give it a like and share if you like it. And then you also have the Harman Kardon premium sound system up there as well. Now here's your factory brake controller, your auto leveling suspension so you can actually lower it or raise it as off-road mode one, off-road mode two, normal and then entry level where it'll lower the truck so it's easier to get into. Stability control, tow haul, front and rear parking sensors has two USBs, two USB C's and an aux jack. You get the RAM charger remember with that night edition, you also have a 115 volt 400 watt plug-in. You have sliding tray right here with two cup holders, you have keyless entry, remote start, you can lower the truck, you can drop the tailgate, all that good stuff from your key fob. And I'll show you how that tailgate works in just a second. You also have the panoramic vista roof up here so that second row is fixed glass, the front row is a power sunroof and I can actually show you how that works. So that'll open up pretty much all the way and because it's tinted when you have it open it's a lot brighter in here.  So really cool stuff. And we'll take a quick look at the back seats. So back here we have the second row heated seats, they are heated on the outboard side meaning that this side and the driver's side here has the heated element in it. You also have the latch child safety system, now notice on the crew cabs you get three latch sets. So like one here, one in the middle and then one at that side so you could fit up to three car seats in here if you squeeze them in. Power sliding rear window with the built-in rear defrost, you get the speakers up there with the Harman Kardon sound system. There your heated seat buttons, two USBs, two USB C's, you also get the RAM bin where you can put extra storage stuff in there and it has a bin in here that comes out. For easy cleaning it also has a little ruler on there up to 26 inches on that side and then the other side, or that's centimeters on this side and then on that side you have up to 15 inches on that side, sorry about that. But that's removable so you can do easy cleaning which means you can put ice and drinks in there and use it for like a mini cooler along with your RAM boxes you could do that too. So this seat reclines and you can see just how much it reclines. There's a little handle under here that'll put it back upright and then what's also cool about these seats is that the headrests do go down for better visibility when nobody's riding back there. They do fold up as well and you get this storage tray where you can put that up and then stuff's not going to roll around on you. Back doors are trimmed out the same way as the front doors, you do get the child's safety locks and then I'll show you the back and we'll start it up with the key fob on the remote start one second here. Alright we'll start it up with the key fob as promised and you get the remote start button there you press it twice. If it's going to go it'll beep twice on you to let you know that it accepted the remote start. If it only beeps once it won't start for you. Now I'll show you how that tailgate works as well you just push this twice and that tailgate goes down it's got a shock down assist so it's never going to slam on you and it's real light. You get the bed rail storage system with the tie down cleats so they move and you can latch them down for better tie down areas. Really a nice quiet truck. We'll take a quick look under the hood and then we will do a final walk around with all the lights on. Under the hood we have the 5.7 liter V8 Hemi motor with the MDS, shuts off, pour the cylinders on the highway to get you a better fuel economy that's how they achieve that 21 miles per gallon. Once again 395 horsepower, 410 foot pounds of torque, you got your emission sticker right here. Everything that you need to do is labeled in yellow, brake fluid, engine oil, washer fluid and coolant and the Hemi's been a really good motor for Ram. This truck has been a motor trend truck of the year I believe three years in a row, first time that that's ever happened and really a good looking truck and as promised I'll do a final walk around with all the lights on here so you have the LED headlamps which these are the headlamps down there, right in there. These are the LED running lights and then your fog lamps down here are reflector LEDs as well. So we'll do one more final walk around.

Dear students, in this topic we shall discuss in detail the vascular resistance to flow. The resistance that must be overcome to push blood and create flow through the circulatory system is known as vascular resistance. There are two types of vascular resistance. The resistance offered by the systemic circuit is known as systemic vascular resistance and the resistance offered by the arteries or blood vessels of pulmonary circuit is known as pulmonary vascular resistance. The systemic vascular resistance is used in the calculations of blood pressure, blood flow and cardiac functions. Dear students, many factors affect the vascular resistance. The two major factors are the elasticity of vessel wall and the diameter of the vessel. The decrease in blood vessel diameter by vasoconstriction increases vascular resistance. If the diameter of the vessel increases by vasodilation, vascular resistance decreases. Now we shall discuss the method and equation for calculation of vascular resistance. Vascular resistance is calculated by a modified form of Poisewell's equation. It is read as the resistance to blood flow is equal to the 8 L eta divided by pi r raised to power 4, where r is the resistance to blood flow.  From this equation, it is evident that resistance to flow is inversely proportional to the fourth power of radius of the vessel. So, vascular resistance is the lowest in larger vessels, whereas in narrow capillaries, vascular resistance is the highest or maximum.
