A simple pin-connected truss is loaded and supported as shown in Figure P1.12. 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.

A simple pin-connected truss is loaded and supported as
shown in Figure P1.12. 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.
