Answer: The assembly is supported by journal bearings at A
Chapter 21, Problem 21-46(choose chapter or problem)
The assembly is supported by journal bearings at A and B, which develop only y and z force reactions on the shaft. If the shaft is rotating in the direction shown at \(\boldsymbol{\omega}=\{2 \mathbf{i}\} \ \mathrm{rad} / \mathrm{s}\), determine the reactions at the bearings when the assembly is in the position shown. Also, what is the shaft’s angular acceleration? The mass per unit length of each rod is 5 kg/m.
