Truss Problem: Consider the truss shown in the figure below. The support at point A is a pin. The support at point C is a roller.
(i) Draw a free-body diagram of the entire truss structure. Assume the mass of the truss members is negligible compared to the forces supported by the truss.
(ii) Draw a free-body diagram associated with joint B.
(iii) Calculate the forces associated with members AB and BC. Be sure to specify whether the members are in tension or compression.
