FBD and equilibrium on Frame (bending moment, axial load) and Truss (axial load).
Sketch a free-body diagram of each element in the figure. Compute the magnitude and direction of each reaction force. Hint (a) Supports are pinned or hinged and it’s a frame, carrying both bending moment and axial load. Hint (b) It’s a truss, carrying only axial loads, and external loads are applied only at joint(s). Step 1: Find RA and RE. Step 2: Find components of RC on link 4 and RD. Step 3: Find components of RC on link 2.
