Problem 3 (35 pts) - 2D Rigid Body Equilibrium The system shown to the right is in equilibrium. The bent bar is supported by a pin at point D and the cable ABE passes over a frictionless pulley at point B. For a = 3 in, and P = 90 lb, determine the tension in cable ABE and the support reaction at point D in both cartesian components and as a single force with magnitude and direction. B D E C A P -5 in.- -7 in. 12 in.
