Question

A simple pin-connected truss is loaded and supported as shown in the figure. The load P is 200 kN. All members of the truss are aluminum pipes that have an outside diameter of 115 mm and a wall thickness of 6 mm. Determine the normal stress in each truss member. Assume truss dimensions of a = 12.0 m, b = 7.5 m, and c = 6.0 m.
