The frаme BCDEF is subjected tо а trаpezоidal distributed lоad on segment BCD, a point load, P = 100 N, at point D, and a couple moment M = 20Nm at point E, which is the midpoint of segment DF. It is held in equilibrium by a pin at point C and a cable which passes through a frictionless pulley at point A and is attached to the frame at points B and F, as shown in the figure. Find the support reactions at point C and the tension in the cable. Take a = 2m and θ = 30o. Include a Free Body Diagram to receive full points.
