Question: Derive the total potential energy for the prismatic circular cross-section torsion bar shown in Figure P5-47. Also determine the equivalent nodal torques for the bar

Derive the total potential energy for the prismatic circular cross-section torsion bar shown in Figure P5-47. Also determine the equivalent nodal torques for the bar subjected to uniform torque per unit length (lb-in./in.). Let G be the shear modulus and J be the polar moment of inertia of the bar.
