The ramp of a ship has weight W and center of gravity at G. Determine the cable force in CD needed to just start lifting the ramp, (i.e., so the reaction at B becomes zero). Also, determine the horizontal and vertical components of force at the hinge (pin) at A.

Given:

W = 200 lb a = 4 ft

θ = 30 deg b = 3 ft

φ = 20 deg c = 6 ft
