Dynamics: Roation about a Fixed Axis and its Forces



Roation about a Fixed Axis and its Forces

If a rigid body is rotating around a fixed axis the tangential and normal components would have to be considered along with the effects of the mass moment. The equations that would be used to solve a problem that has rotation about a fixed axis can be seen below.
