Question

Learning Goal: To use the principle of superposition to determine the total deflection in a cylindrical rod due to a static loading. A steel rod (E= 200 GPa) is subjected to the load shown, where P = 2900 KN. A gap a = 2.00 mm exists before the load is applied. The elongated rod contacts the top surface at C'. Assume the mass of the rod is negligible. The values for the figure below are d = 0.800 m, e = 0.400 m, j= 55.0 mm, and g= 43.0 mm.

please show steps. don't know how to go about solving this problem
