Question

A beam of metal supported at the two ends is loaded at the centre. The depression at the centre is proportional to

• A. $Y^2$
• B. Y
• C. $\frac{1}{Y}$
• D. $\frac{1}{Y^2}$

Answer 1

The correct option is C $\frac{1}{Y}$

c) Depression in beam

$\delta$ = $\frac{W{L}^3}{4Yb{d}^3}$
$\delta$ = $\frac{1}{Y}$
