General Planar Motion with a Center of Mass Reference - Example 6.7-2
The angular motion of a body undergoing general planar motion (i.e. translating and rotating) is described by the following equation, where P is an arbitrary reference point.
∑MP = IPα + rG/P x maP
Explain why, if G is the reference point, the body's angular motion is described by the following equation.
∑MG = IGα
