a The structure shown below is a simplified tower crane. It carries a shipping crate suspended from that has a weight of 95 kN. The main jo DCB (in green has a weight of 23 kN concentrated in the center of the beam. This is pinned to the main body at D and is supported by a cables that is routed through pulleys at F and G and is attached to a concrete counterweight J. The main body AEFG in yellow) is fixed to the ground at A F h3 G ө7 E h2 D С B 11 12 13 h1
