Question
For the three bolt system shown in the figure, the joint transmits a shear load of (applied as shown). the bolt material has shear yield strength of . For a factor of safety of 2, the minimum metric specification required for the bolt is
Correct answer
(B) M10
Solution
All three bolts are in single shear and share the load equally.
1.Load per bolt:
2.Allowable shear stress:
3.Required diameter:
M8 (8 mm) is too small; the smallest listed size that satisfies mm is M10. M12 and M16 also work but are not the minimum.Answer: (B) M10Continue learning with Success Tracker
