The steel cable is hoisting a 2,000N weight. Assume the weight is not accelerating and the cable is parallel to the sides as shown in the figure. Assume also that the pulley is frictionless. 3m 2,000N 3m 3m 3m Determine the reaction at B, in N. Determine the force in member AC, in N. Determine the force in member DF, in N.

The light boom AB is attached to a vertical wall by a ball and socket joint at A and supported by two cables at B. A force P is applied at B where P = 18i - 15j kN.Note that the reaction force at A acts along the boom because it is a two-force member. Calculate the magnitude of the reaction force at A in kN.

Determine the magnitude of the moment of P about the origin (point O) in Nm. Answer: Answer

Two bars connected by a sliding block are shown in the figure. If the effect of friction is not taken into account, perform the following operations: 1.1 Draw the Free Body Diagram (F.B.D.). (1.0 point) 1.2 Determine the moment Ma​ necessary to keep the system in equilibrium. (1.0 point) 1.3 Determine the magnitude of the reaction at support A. (1.0 point) 1.4 Determine the magnitude of the reaction at support B. (1.0 point) 1.5 Determine the magnitude of the reaction at joint C. (1.0 point)
