Question

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.

Expert Solution

Step 1

Overall equilibrium :

$\sum F_{y} = D_{y} - p = 0 D_{y} = p = 200 K N \sum M_{y} = P a + B_{a} c = 0 B_{a} = - \frac{P a}{c} = \frac{P \times 12}{6} = - 2 P = - 400 K N \sum M_{B} = P a - D_{x} c = 0 D_{x} = 2 P = 400 K N$
