Q. Which bolt is under maximum shear stress?

(A) 1
(B) 2
(C) 3
(D) all are under equivalent shear stress
Correct : Option (C)

Explanation: 
 primary shear force acts equally on the three bolts in the vertically upward direction while the moment is cw along cg so its effect on bolts will be acw. hence secondary shear force acts vertically upward on bolt 3 and vertically downward on bolt 1.
