Question

A rubber cube of side 5 &#160; cm has one face fixed while a tangential force 1800 &#160; N is applied on its opposite face. If modulus of rigidity of rubber is 2 . 4 &#215; 10 6 &#160; N &#160; m - 2 , then the lateral displacement of the strained face is______.

Recall the formula of modulus of rigidity,

$η = \frac{F}{A} \times \frac{L}{l} = \frac{1800}{25 \times 10^{- 4}} \times \frac{5 \times 10^{- 2}}{l} = 2.4 \times 10^{6} l = \frac{1800}{25 \times 10^{- 4}} \times \frac{5 \times 10^{- 2}}{2.4 \times 10^{6}} = 15 mm$
