Q-4: 1.9 m B Two cables are used to secure the 2.5 m overhang boom in position and support the 8000 N load. If the resultant force is directed along the boom from point A towards O, determine the magnitudes of the resultant force and forces FB and Fc. Set x = 3.8 m and z = 4.3 m. FB FC 6.2 m %3D 8000 N

A lug wrench is used to tighten a square-head bolt. If 66-Ib forces are applied to the wrench as shown, determine the magnitude F of the equal forces exerted on the four contact points on the 1.2 in. bolt head so that their external effect on the bolt is equivalent to that of the two 66-Ib forces. Assume that the forces are perpendicular to the flats of the bolt head.

The system shown consists of three cables; 1, 2 and 3. Cable 1 passes through a frictionless pulley. A 6 kg mass is suspended. Determine the force in cable 3 considering the following data: y1 = 1.3 m, y2 = 1.1 m, y3 = 1.8 m, and x1 = 2.7 m.

A lug wrench is used to tighten a square-head bolt. If 59-lb forces are applied to the wrench as shown, determine the magnitude F of the equal forces exerted on the four contact points on the 1.2 in. bolt head so that their external effect on the bolt is equivalent to that of the two 59-lb forces. Assume that the forces are perpendicular to the flats of the bolt head.

2. The homogeneous bar AB weighs 25 lb. Determine the forces acting on the bar at A and B. Neglect friction. 60° A

The force vector F has a magnitude of F = 460 lb and acts at point A at an angle = 11° with respect to vertical as shown. The force F is balanced by the tension forces parallel to the two rods AC and AB such that the vector equation F + FAC + FAB 0 is satisfied. Determine the tension forces in the two rods in Cartesian components. b C (CC) Oo BY NC SA 2013 Michael Swanbom a b NF Values for dimensions on the figure are given in the following table.
