A wall bracket is attached to the wall by means of 2 identical bolts, one at A and one at B. The force of 20kN acts at a distance of 400mm. Bolt A lies at a distance of 50mm from axis of tilt and bolt B 500mm. Allowable shear stress in the bolts is 100N/mm² and tensile is 40N/mm². Find the ratio of the effective tensile load to which the two bolts are subjected.

Find the ratio of the effective tensile load to which the two bolts are subjected. Correct Answer 10
F₁=Pel₁/2(l₁² + l₂²) and F₂= Pel₂/2(l₁² + l₂²) or F₁/F₂ =l₁/ l₂.
