Problem 4: A ball and socket joint A and two wires are used to hang a sign of mass 120 Kg (1177 N). The CG of the sign is at G and is aligned with the middle point of bar AB. Assume the signboard supports at points A and B. Draw a FBD of bar AB and show all forces acting on it. (Compute only in N and m.) 2 m m 2 m m I'm •G 1m
