Using the method of joints, determine the internal forces in each member of the truss. Show your results in a sketch of the truss along with the magnitudes of the internal forces. Indicate whether each member is in tension or compression. A 40 kN B F 20 kN 60 kN ↓c с G 4 at 8 m = 32 m - 30 kN H D E 6 m

The truss shown is designed to support a staircase. For all questions, indicate whether the members are in tension or compression. Assume that all joints are pinned. Use the method of sections for each part.a. Determine the force in members EG, FG, and HFb. Determine the force in members EF and DF
