Question

A beam of square cross-section (B x B) is used as a beam with one diagonal horizontal. The location of the maximum shear stress from the neutral axis will be at distance of

• A. zero
• B. $\frac{B}{4}$
• C. $\frac{B}{4\sqrt{2}}$
• D. $\frac{B}{8}$

Answer 1

The correct option is C $\frac{B}{4\sqrt{2}}$

The diagonal $B\sqrt{2}$. The location of maximum shear stress from neutral axis is $\frac{1}{8}$ length of diagonal i.e. $\frac{B}{4\sqrt{2}}$.
