9-32. Determine the force in member EC of the truss. AE is constant. 3 m 3 m E 4 m Prob. 9-32 10 kN

4-46. If the gap between C and the rigid wall at D is initially 0.15 mm, determine the support reactions at A and D when the force P = 200 kN is applied. The assembly is made of A-36 steel. A -600 mm P 50 mm B 600 mm 25 mm Prob. 4-46 C -0.15 mm

3.) please help with problem and provide free body diagrams when needed

Determine the force in each member of the space truss and state if the members are in tension (T) or compression (C). The truss is supported by ball-and-socket joints at A, B, and E. Set F = {-200i+ 400j} N. Hint: The support reaction at E acts along member EC. Why? 5 m -2 m- 1 m- 1.5 m. B D 2 m F E
