The tower crane shown is supporting a hook load, P, of 30 kN. The tower (vertical part) is uniform and weighs 40 kN, the boom (horizontal part) is also uniform and weighs 30 kN, and the counterweight, W, weights 50 kN. There is a horizontal wind load that results in a force of 20 kN acting to the right at the midheight of the tower. For all the forces given, determine the equivalent force-moment system at A. 40 m. 6 m 25 m 2 m P A
