2. Find the equivalent load produced on the concrete by the prestressing tendons. Show the equivalent loads (forces and moments) and their numerical value acting on the centerline of the concrete member (c.g.c). [i.e., Draw the free body diagram]. Show the moment diagram due to prestressing. (Assume constant tendon forces throughout the beam - no prestress losses: e.g., no friction) (Assume no gravity loads.)
