The lid of a roof scuttle weighs 93-lb. It is hinged at corners A and B and maintained in the desired position by a rod CD pivoted at C, a pin at end of D of the rod fits into one of several holes drilled in the edge of the lid. Assume that the hinge at B does not exert any axial thrust. The value of a = 50°. y 26 in. D 15 in 7 in. 32 in. For the position shown, determine the magnitude of force exerted by rod CD. (You must provide an answer before moving to the next part.) The magnitude of force exerted by rod CD is lb.
