Question

A steel shaft is fixed from rotating at the ends of the shaft (A and B). Two forces, P, are applied at the ends of the vertical arms that are welded to the shaft at C, where P is 5 kN. If the reaction torque at B is given to be -800 N-m, a.Find the reaction torque at A. b. Find the internal torque in the shaft by cutting between A and C and then C and B and applying static equilibrium. c. Plot the torsional moment diagram.
