A boom hinged at the base of a vertical mast is used to lift a 2000 load. Find the tension in the cable and the reaction R the end of the boom. The angle of the boom is 40 degrees with the horizontal and the cable is 60 degrees with the vertical mast. Show complete solution including FBD

The spring in Fig. is unstretched when e = 6 = 15°. Find the angle 6 for equilibrium if mg = 60 kg, mp = 25 kg, L=1 m, and & - 750 N/m. Assume that the masses of the bars are negligible. D mp

Draw the free body diagram for this problem: The boom of the wall crane 4m long is held at right angles to the wall by a wire that is attached to the wall 3m above the foot of the boom. If the load lifted is 45000N, find the tension in the wire and the compression force in the boom. Neglect the weight of the boom.

Q/1: A 10 m long vertical mast has a ball-and socket joint at A, and it is supported by two (2) cables, BD and BC as shown in Figure 1. A force 4 kN is applied at G. Draw the free body diagram (FBD) for the rigid body and determine: (a) The tensions in cables BD and BC (b) The reactions at the ball-and-socket joint at A (c) The projection of T, along the line BE (d) The angle between cable BD and line BE (e) The moment of T, along line CF T2 4 kN 5 m B 5 m T₁ 4m-F 74 m 12m x
