Hey Tribal, good to see you again. Here's the solution for part (a) of the problem. Part (a) (i): Show that F = 2sqrt(3)mg. Step 1: Identify the forces and geometry. The uniform rod AB has length 3a and mass m. Its weight mg acts downwards at its midpoint, which is at a distance of 1.5a from the hinge A. The rod AB is horizontal. The light rod CD connects point C (vertically below A) to point D on AB. The distance AD = (a)/(2). The angle ACD = 30^. Since C is vertically below A and D
