The truss, shown in figure (3), is being held in place by a pin at F and a roller at A. Use the method of joints or the method of section to determine the forces in members BE, and BD. 120 kN 4.5 m 3 m 1.5 m A C G. 2 m 2 m 2 m E 60 kN B.

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)
