The hatch door has a weight W and center of gravity at G. If the force F applied to the handle at C has coordinate direction angles of α, β and γ, determine the magnitude of F needed to hold the door slightly open as shown. The hinges are in proper alignment and exert only force reactions on the door. Determine the components of these reactions if A exerts only x and z components of force and B exerts x, y, z force components.

Given:

W = 80 lb

α = 60 deg

β = 45 deg

γ = 60 deg

a = 3 ft

b = 2 ft

c = 4 ft

d = 3 ft
