Chapter 6, Problem 54P

Determine the force in each member of the loaded truss. The forces are positive if in tension, negative if in compression. Assume F = 2460 N, a = 2.6 m, b = 5.2 m, 0 = 46°. B Ө a Ө b Ө D F

Using the attached image, determine the force in each member of the truss and state if the members are in tension or compression. Set P1= 2 kN and P2= 1.5 kN. Use method of joint.

Given the magnitudes of the applied forces on the truss shown below are 0 = 2 kN, P = 3 kN, Q = 3 kN, R = 5 kN, S = 3 kN, T= 4 kN and U = 4 kN. kN P kN kN R kN S kN T kN KN H. 0.4 m K A 0.8 m 0.8 m 0.8 m 0.8 m 0.8 m 0.8 m Determine the forces in members EF, CF and EG.
