Q-1 The hatch door has a weight = 80 lbs and center of gravity at G. If the force F applied to the handle at C has coordinate direction angles α = 600, β = 600 and γ = 450 determine the magnitude of F needed to hold the door slightly open as shown. If the hinge at A becomes loose from its attachment and is ineffective, what are the x, y, and z components of the reaction at hinge B. a = 3 ft, b = 2 ft, c = 4 ft and d = 3 ft (20 Marks)
