Solve Prob. 7-28 assuming that each beam has a uniform weight of 150 lb/ft.

Prob. 7-28:

The jack AB is used to straighten the bent beam DE using the arrangement shown. If the axial compressive force in the jack is 50001b, determine the internal moment developed at point C of the top beam. Neglect the weight of the beams.
