CalcPad - Rotation and Balance Problem Sets
This collection of problems focuses on the analysis of situations involving a rigid object rotating in either a clockwise or counterclockwise direction about a given point, as well as the use of the torque concept and equation to analyze a beam in order to determine the conditions for which it will or will not rotate. The object's rotation speed may be increasing, decreasing, or remaining constant.
