Energy torque work power pdf
Power is the rate at which work is done, or energy is transmitted. Torque is the tendency of a force to rotate an object about an axis (or fulcrum or pivot). Just as a force is a push or a pull, a torque can be thought of as a twist.
In physics, energy is defined as the amount of work that can be performed by force, whereas power is defined as the rate at which work is performed. Definition Energy is the capacity to do work. Energy is power integrated over time. Power is the rate at which work is done, or energy is transmitted

The residual limb cannot produce as much force due to less muscle. Due to decreased ability to do mechanical work with the residual limb, mechanical work increases on the sound side to compensate. The amount of mechanical work is highly dependent on the surgeon length of
The work done is the area under the torque-angle graph. For a given pair of values W = Tθ/2 The strain energy stored is equal to the work done hence U = Tθ/2 From the theory of torsion (not covered here) θ = TL/GJ G is the modulus of rigidity and J is the polar second moment of area. J = πR4/2 for a solid circle. Substitute θ = TL/GJ and we get U = T2L/2GJ Also from torsion theory T = τJ

Calculate the torque provided at the shaft of an electric motor that develops an output power of 3.2 hp at 1800 rev/min.
Energy is a measure of how long we can sustain the output of power, or how much work we can do; power is the rate at which we do the work. One common unit of energy is the kilowatt-hour (kW-hr). You learned in the last section that a kW is a unit of power. If we are using one kW of power, a kW-hr of energy will last one hour. If we use 10 kW of power, we will use up the kW-hr in just six minutes.

Power is the rate of doing work or the rate of using energy: P=Work/t=Energy/t , where t is time. Although casually the terms energy and power are often used interchangeably, technically they have different meanings.
Relationship between torque, power, and energy If a force is allowed to act through a distance, it is doing mechanical work . Similarly, if torque is allowed to act through a rotational distance, it is doing work.

Work . Work is a special name given to the (scalar) quantity = ∫ → ⋅ →. where is work and is force on the object and is displacement. Essentially this integral is the component of the force in question in the direction of the displacement, times the displacement.
How Force Power Torque and Energy Work
Power is the amount of energy delivered per unit of time, this is high power requiere a lot of energy delivered in a short period of time. The equation is Power = Torque x RPM ( all unit to be consistent).
ENERGY is defined as the CAPACITY of a body to do WORK, by virtue of the position or condition of the body. Now suppose there is a 150-pound plate of steel on your bench, resting on four blocks which are 2 inches tall (so the space between the bottom of the plate and the bench is 2 inches).
Power is the rate at which work is done or, equivalently, it is the rate at which energy is converted from one form to another. And here, “rate” means simply “how fast.” The formula for calculating power is

Although the work done is the same in both cases There is considerable confusion between torque, power and energy. For example, the torque of an engine is sometimes incorrectly described as its ‘turning power’. Torque and energy have the same dimensions (i.e. they can be written in the same fundamental units), but they are not a measure of the same thing. They differ in that torque is a
One of the textbooks that I have read uses a very familiar example to illustrate that torque can do work. The example is that of a person pulling on the rope on a power mower or outboard engine to try to get it

Torque is a force that tends to rotate or turn things. You generate a torque any time you apply a force using a wrench. Tightening the lug nuts on your wheels is a good example. When you use a wrench, you apply a force to the handle. This force creates a torque on the lug nut, which tends to turn the lug nut.
