In a rivet joint thickness of the plate is t and the length of the margin is m. If the permissible shearing stress of the plate is τs, find the shear strength of the joint at the margin.

In a rivet joint thickness of the plate is t and the length of the margin is m. If the permissible shearing stress of the plate is τs, find the shear strength of the joint at the margin. Correct Answer 2mtτs

Shearing strength at the margin is the product of the permissible shear stress and the area resisting the shear force at the margin. Area resisting the shear force at the margin is 2mt and the permissible shear stress is τs. Hence the shear strength at the margin is 2mtτs.
