## Shear vs Tensile Strength

If a stainless steel bolt has a tensile strength of 80,000 psi, estimate the shear strength in psi.

Expand Hint
Tensile strength is the max stress a material can be pulled or stretched before breaking. Shear strength is the max stress a material can handle from a shear load (think a sliding along a plane parallel to the force) before breaking.
Hint 2
As a general rule, a material’s shear strength is roughly 60% of its tensile strength.

As a general rule, a material’s shear strength is roughly 60% of its tensile strength:
$$(0.6)TS\simeq Shear\:Strength$$$where $$TS$$ is the tensile strength. $$(0.6)(80,000psi)\simeq 48,000\:psi$$$
$$\simeq 48,000\:psi$$\$
