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 effective tensile force acting in the two bolts.
A. Bolt B=792.07N & Bolt A=792.07N
B. Bolt B=792.07N & Bolt A=7920.8N
C. Bolt B=7920.8N & Bolt A= 792.07N
D. Bolt B=7920.8N & Bolt A=7920.8N
