How to Improve Your Power-to-Weight Ratio The more power an athlete has per pound, the higher the power-to-weight ratio. Generally, athletes measure their power-to-weight ratio by pounds per watt. They take the amount they weigh and divide it by the amount of power they can produce, measured in watts.

Brain-to-body mass ratio Brain-to-body mass ratio. Brain-to-body mass ratio, also known as the brain to body weight ratio, is the ratio of brain mass to body mass, which is hypothesised to be a rough estimate of the intelligence of an animal, although fairly inaccurate in many cases.

What is Compression Ratio? Engines with higher compression ratios are generally considered better because they create more power while still maintaining efficiency. Ad. To calculate the compression ratio of an engine, an engineer would first calculate the volume a cylinder in the engine can hold when the piston is at the bottom of the cylinder.During one stroke of the engine, the piston moves from the bottom up toward the top and compresses the air-fuel mixture.0 hilariously insightful foreign words. Compression ratio refers to the volume, or amount, of an air and fuel mixture that the combustion chamber in a combustion engine can hold when it is empty and at its largest size compared to the volume it holds when the mixture is compressed down to the smallest size possible.

- Power = Strength x Speed. When performing a sprint, you can think of power as the amount of force that you apply into the ground with each stride. Obviously the greater the force, the more ground you're going to cover with each stride. This is what is responsible for your stride length.

- WORLD´S FIRST MEGACAR. The One:1 was introduced in 2014. Seven examples, including one prototype, were built during 2014 and 2015. This was one of the most exclusive production car programs ever envisaged in the car industry. The hp-to-kg curb weight ratio is an astonishing 1:1. This is the “dream” equation, previously thought impossible when it comes to fully road legal and usable sports cars.

- Mass and Weight. Weight is the force of gravity exerted upon a mass. Weight and mass are related, but are not the same. An object's weight depends upon two things: 1. its mass. 2. the acceleration of gravity in the part of the. universe it occupies.

Cycling power-to-weight ratio (PWR) Climbing a big climb can take over two hours. You need to be able to maintain your ratio for that time span. Some (professional) cyclists can produce 6.5 watts/kg during half an hour but may only be able to produce 6 watts/kg for an hour. So you need to know what your maximum sustainable power is.

Standing wave ratio The power standing wave ratio (PSWR) is defined as the square of the VSWR, however this terminology has no physical relation to actual powers involved in transmission. SWR is usually measured using a dedicated instrument called an SWR meter.

- It has 201 horsepower at its disposal, and since there’s not much car to move, the Veloster offers a power-to-weight ration of just 13.930. This bundle fun can also be had for just under $22,000, making it a hell of a bargain too.

- Electric engines have a much better power to weight ratio than turbine or reciprocating piston engines. The problem with an electric truck is the fuel energy density. This means to get the same range, Lion batteries requires 45/0.72 = 62.5 times the weight and 36.4/2.23 = 16.3 times the space of diesel fuel.

- The Power Factor of your system is the cosine of the angle between the current and the voltage. A power factor of close to 1 means that the voltage and current are close together. A low power factor will mean that your voltage and current are far out of phase.

Compression ratio The compression ratio of an internal-combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber from its largest capacity to its smallest capacity.

what is the best strength to weight ratio? For spaceframe structures that are extremely stiff (fully constrained truss-type frames), strength-to-weight becomes the limiting parameter, as long as buckling has been adequately addressed. Metals with the highest strength-to-weight ratio are maraging steels and several metastable Beta titanium alloys.

Power The power rating indicates the rate at which that machine can do work upon other objects. Thus, the power of a machine is the work/time ratio for that particular machine. A car engine is an example of a machine that is given a power rating. The power rating relates to how rapidly the car can accelerate the car. Suppose that a 40-horsepower engine could accelerate the car from 0 mi/hr to 60 mi/hr in 16 seconds. If this were the case, then a car with four times the horsepower could do the same amount of work in one-fourth the time.

- Power gain is defined as the ratio of the output power to the input power in dB. Assume that the input power is 10 mW (+10 dBm) and the output power is 1 W (1000 mW, +30 dBm). The ratio will be 1000/10 = 100, and the power gain will be 10×log 100 = 20 dB.ower gain is defined as the ratio of the output power to the input power in dB.

- This is the exact power that your engine can produce. That is the crankshaft that comes out of the crankcase. It is the amount of energy required to lift 550 pounds, one foot, in one second. Therefore we can see that the greater the horsepower the more powerful the engine and the faster we can gear the Kart to go.

How to Calculate and Convert Rear Wheel Horsepower 1 Multiply Base Horsepower by the Appropriate Percentage-Automatic transmissions are said to lose 20% of the power from the engine to the wheels, while manual transmissions lose 15%. 2  To determine rear whp, multiply the base horsepower by 0.80 if you have an automatic transmission and 0.85 for a manual transmission. Convert Horsepower to Other Measures - 1 horsepower = 550 foot-pounds/second, 33,000 foot-pounds/minute, 42.44 Btu/minute, and .7456999 * kilowatts.

Compression Comprehension This, along with as high a compression ratio as the fuel will stand, means significantly higher pressures on the power stroke. Moving on to the compression stroke itself, we find that the higher the compression ratio is, the higher the resultant combustion pressure is. Not only that but the charge also burns faster, thus necessitating less advance for an optimal burn event.

Supplement Conversion Ratio Most cattle producers are familiar with the term feed conversion.. Advertisement. Most cattle producers are familiar with the term feed conversion.. It is simply the amount of feed an animal consumes as compared to the amount of body weight gained, expressed as a ratio. Feed conversion ratios in the neighborhood of 6:1 (6 lbs of feed per pound of gain) are common in modern beef cattle feedlots. Stocker cattle producers are also interested in feed conversion, but the calculation is a little different.

Pulleys and Belts The ratio of the pitch diameters is called the drive ratio, the ratio by which torque is increased and speed is decreased, or vice versa. Power is the product of speed and force, or in the case of things that spin, speed and torque.

- The compression ratio is the measurement of multiplied atmosphere by which the fuel and air charge is squeezed. Atmosphere is roughly 14.7 pounds per square inch. The compression ratio is just one of many design factors affecting overall performance. Imagine you take a firecracker, and place it in your open palm.

Torque vs. Horsepower If the test engine produced 80 ft lbs of torque the clutch has to handle 120 ft lbs of torque (80 ft lbs times 1.5 primary drive ratio). The output from the transmission in first gear is 120 x 3.0 or 360 ft lbs.The torque is further multiplied by the 3.0 final drive ratio to 1080 ft lbs.f our bike weights in at 500 lbs plus a 200 lb load for fuel and rider, that's 700 lbs of weight. From one of Newton's laws of motion: f = ma or more useful for us: a = f/m. a = 829/700 = 1.18 g's.
