You must solve all questions. Weight is supported by a wooden space truss and a rope. The truss is connected to the side of a building by a ball and socket joint at point B, frictionless supports at joints A and C, and the rope between D and E. The weight causes a vertical force of 520 grams. Calculate the forces in each member, the reactions at joints A, B, and C, and the tension in the rope.
