The signboard with a mass of 100 kg (with centre of mass at point G) is to be attached to the rod AB as shown in Figure Q1. Rod AB is joined with ball-socket to point A. Point B is supported by two rods BC and BD. The location of each point is revealed as A (0,0,0), B (0,2,0), C (1,0,2) and D (-2,0,1). Solve the followings: (i) Detemine the x, y and z components of force reaction at joint A, and (ii) Calculate the tension within the rods BC and BD.
