    + The Work of a Couple 1 of 8 > Review Part A Learning Goal: To be able to calculate the work done by a couple on a rigid body. When a body subjected to a couple moment, M, undergoes general planar motion, the two couple forces do work only when the body undergoes a rotation. When the body rotates in the plane through a finite angle 0 (measured in radians) from 01 to 02, the work of a couple...
