Comparison of two rotating systems with identical mass M and length L.
Comparison of two rotating systems with identical mass M and length L.
System 1 consists of a uniform rod of mass \(M\) and length \(L\) pivoted at one end. System 2 consists of a massless rod of length \(L\) with a point mass of mass \(M\) attached to the end opposite the pivot. Both systems are held horizontally and released from rest at time \(t = 0\). What is the ratio \(̑_1 / ̑_2\) of the magnitude of the initial angular acceleration of System 1 to the magnitude of the initial angular acceleration of System 2?
