Please solve them prior to the tutorial time. Only the problems indicated with * will be discussed during the tutorial time. Solutions to this problem set will be posted at the Course Website. 1. [Use Vector Formulation] The particle shown in Figure 1 is in equilibrium under the action of four forces as shown in the free-body diagram. Determine the magnitude and the coordinate directions angles of the unknown force F4 . 2.* [Use Vector Formulation] Calculate the tension in each of the three cables that support the 1500 kN weight. Figure: 1 Figure: 2 3. [Use Vector Formulation] The uniform 7m steel shaft has a mass of 200kg and is supported by a ball-and-socket joint at A in the horizontal floor. The ball end B rests against the smooth vertical walls as shown in Figure 3. Compute the forces exerted by the walls and the floors on the ends of the
