Determine the size of the bolts if yield strength of bolt is 400N/mm² and factor of safety is 4. The bolts are equidistant having separated by 60mm and the margin to the left and right is 25mm. Also P=5kN acts at a distance of 200mm from the channel. |
A. | 14.34mm |
B. | 13.44mm |
C. | 15.44mm |
D. | 12.66mm |
Answer» B. 13.44mm | |
Explanation: clearly bolt 3 is under maximum shear stress. net shear stress= primary shear stress + secondary shear stress or τ= (1000+6100) n or 0.5 x 400//4=7100 x |
