Question: Draw the influence line for the force in member IC of the bridge truss. Determine the maximum force (tension or compression) that can be developed

Draw the influence line for the force in member IC of the bridge truss. Determine the maximum force (tension or compression) that can be developed in the member due to a 5-k truck having the wheel loads shown. Assume the truck can travel in either direction along the center of the deck, so that half the load shown is transferred to each of the two side trusses. Also assume the members are pin connected at the gusset plates.
