Problem 349 The truss shown in Fig. P-349 is supported on roller at A and hinge at B. Solve for the components of the reactions.
Solution 349
$24A_V + 16(240) = 36(400) + 12(600)$
$A_V = 740 \, \text{ lb}$ answer
$\Sigma M_A = 0$
$24B_V + 12(400) = 16(240) + 12(600)$
$B_V = 260 \, \text{ lb}$ answer
$\Sigma F_H = 0$
$B_H = 240 \, \text{ lb}$ answer
