A flange of radius 200mm is fastened to the machine screw by means of four cap screws of pitch circle radius 150mm. The external force P is 20kN which is loaded at 160mm from the machine screw. There are two dowel pins to take shear load. Determine the core diameter of cap screw if permissible tensile stress in cap screw is 40N/mm².
a) None of the listed
b) 11.21mm
c) 12.33mm
d) 14.12mm
Answer: c
Explanation: Maximum tensile force=4777.6N or πd² x σ/4=4777.6N.
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 radius of Mohr circle which can be made from the shear stress and tensile stress acting on bolts.(Consider bolt...
