Expert Solution
Step 1

Given:

The mass of the uniform rod is, m=23 kg.

The acceleration due to gravity is, g=9.81 m/s2.

Tension in cable BC is, TBC.

y-component of the reaction at A is, Ay.

x-component of the reaction at A is, Az.

z-component of the reaction at A is, Ax.

The normal reaction at point B is, RB.

The free body diagram of rod is given below,
