Calculate the forces in members AC, AD, and DE for the loaded truss. Restraining link BC is horizontal. Forces are positive if in tension, negative if in compression. B Answer: AC = 3' AD = i i DE = i C 3' 600 lb D 3' E lb lb lb

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
