Q1: Determine the magnitude of the force on the pin at A for the boom shown in Fig. 1. Neglect the size of the collars at D and B and set the weight of the boom = 200 N, F1 500 N and F2 = 485 N. Q2: Determine the magnitude and the direction (measured clockwise from the positive y-axis) of the force F shown in Fig. 2 that will cause the resultant R of the four applied forces to be directed to the right with a magnitude of 9 KN. Q3: Determine the moment of each of the three forces in Fig. 3 about point A. 20 kN 11 kN 7 kN 5 4 30 30° 1m Fig. 2 1.5 m F = 300 N F = 250 N 30 60° 30 -2 m 3 m F1 Fig. 1 4 m B F= 500 N Fig. 3
