In mechanics, Varignon's theorem deals with this quantity. When a system of forces has a nonzero value for this quantity but no resulting force, it is called a "couple." This quantity can be measured in units of newton metres or joules per radian. It can be defined as the cross product of displacement and force, or the time derivative of angular momentum. It is also known as "moment." For 10 points, name this measure of h
