The assembly is supported by journal bearings at A and B, which develop only y and z

Chapter 21, Problem 21-47

(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 A is subjected to a couple moment M = 540i6 N # m, and at the instant shown the shaft has an angular velocity of \(\mathbf{M}=\{40 \mathbf{i}\} \ \mathrm{N} \cdot \mathrm{m}\), determine the reactions at the bearings of the assembly at this instant. Also, what is the shaft’s angular acceleration? The mass per unit length of each rod is 5 kg/m.
