Question

According to maximum shear stress criterion, at what ratio of maximum shear stress to yield stress of material does the yielding of material take place?

• A. 2
• B. $2/\sqrt{3}$
• C. $1/\sqrt{3}$
• D. 1/2

Answer 1

The correct option is D 1/2

As per maximum shear stress theory
${\tau }_{max}\le \frac{{\sigma }_y}{2}$

$\Rightarrow \frac{{\tau }_{max}}{{\sigma }_y}\le \frac{1}{2}$
