Best Answer: Torque is a twisting force. It is the power output of an engine at one specific point in time. The first number, 200 in your expample, is the amount of torque. In America is is measured in foot/pounds. The second number, 400 in your example, is the RPM where that torque number occurs.
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.Mathematically, torque is defined as the cross product of the lever-arm distance vector and the force vector, which tends to produce rotation.ust as a force is a push or a pull, a torque can be thought of as a twist to an object.
