Rotational inertia is the resistance of a body to assume angular motion or once assumed to stop. I will return to these confusing scribbles and attempt to clarify them. Torque is expressed in pound-feet. In general, if the forces applied to a body do not all act at a single point, there is the possibility that the body will rotate. If F is in pounds and h is in feet, the units for T will be foot-pounds.
Torque arises from an applied force on an object.
Torque, then, is the product of applied force and lever arm. The larger the unbalanced torque, the more rapid will be the angular motion produced. Torque can be produced even if the entire body is free to move and not affixed at a point of rotation. All Rights Reserved, Dynamic Chiropractic, 2001.
