orque is measured in pounds-feet.
Mathematically, torque is defined as the cross product of the lever-arm distance vector and the force vector, which tends to produce rotation. Loosely speaking, torque is a measure of the turning force on an object such as a bolt or a flywheel. Torque is measured in pounds-feet, meaning a force in pounds acting on the end of a lever measured in feet. For example, if that lug wrench is 2 feet (0.6 m) long, and you put 100 pounds (45.4 kg) of force on it, you are putting 200 pounds-feet (27.65 kg/m) of torque onto the bolt. Read How Force, Power, Torque and Energy Work for more information on torque. Once we're able to measure torque, we can then measure horsepower. Torque is a measure of turning power. Nm stands for Newton Meter. If you have a wrench that's one meter long, and pull at the end with a force of one Newton, the turning force … by the head of the wrench will be one Newton meter. 18 torque units with name like “ * ” — found. Torque can be defined as a turning or twisting action of the force F upon an object. The word torque itself means to twist in Latin. The SI unit of torque is newton-meter (N⋅M). Figure 6-4: Torque on a Rotating Shaft Torque Measurement Torque is measured by either sensing the actual shaft deflection caused by a twisting force, or by detecting the effects of this deflection. The surface of a shaft under torque will experience compression and tension, as shown in Figure 6-4. Torque, moment, or moment of force (see the terminology below) is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist to an object. Measuring Torque and Horsepower. ­­. ­Let's lay down the basics. Horsepower is a measurement of work, meaning a force ap­plied to an object and the displacement of that obj­ect in the direction of the applied force. r is the displacement vector (a vector from the point from which torque is measured (typically the axis of rotation) to the point where force is applied), F is the force vector, × denotes the cross product, θ is the angle between the force vector and the lever arm vector. In physics, torque can be thought of informally as rotational force. Torque is measured in units of newton metres, and its symbol is τ. The concept of torque, also called moment or couple, originated with the work of Archimedes on levers.
