$\huge\underline{\underline{\bf \orange{Question-}}}$

Linear strain and Poisson's ratio for a material are 0.02 and 0.4 respectetively its lateral strain is

$\huge\underline{\underline{\bf \orange{Solution-}}}$

$\large\underline{\underline{\sf Given:}}$

• Linear strain = 0.02
• Poission's ratio = 0.4

$\large\underline{\underline{\sf To\:Find:}}$

• Lateral strain

We know that ,

✪$\large{\boxed{\bf \blue{Poission's\:ratio=\dfrac{Lateral\:strain}{Linear\: strain} }}}$

$\implies{\sf 0.4=\dfrac{Lateral\:strain}{0.02} }$

$\implies{\sf Lateral\: strain = 0.4×0.02 }$

$\implies{\bf \red{ Lateral \: strain = 0.008} }$

$\huge\underline{\underline{\bf \orange{Answer-}}}$

Option (c)

Lateral strain is ${\bf \red{0.008}}$
