Q.2: (25 pts.): The figure below shows a tube welded to a vertical wall; the tube is subjected to the loads $P = 40$ kip, $F = 80$ kip and $T = 60$ kip.in. Calculate the factor of safety in the weld material at point B. Note that the allowable shear stress in the weld material is 140 kpsi.
Point B
5 in
P
2 in
$\frac{1}{4}$ in
T
