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 cable that is routed through pulleys at F and Gand is attached to a concrete counterweight J. The main body AEFG in yellow) is fixed to the ground at A. F h3 G or E h2 D C B 11 12 13 hi
