Question

young modulus of rigidity?

Answer 1

shear modulus ae the modulus of rigidity.
its s.i. unit is pascal although it is represented in gigapascals.
it is one of the several quantities for measuring stoffneess of a material.

Answer 2

$\huge\mathfrak\red{Answer :}$


$\huge\textbf{Young's Modulus (Y) :}$

It is defined as ratio of normal stress with longitudinal strain.

i.e.

Y = $\dfrac{Normal\:Strain}{Longitudinal\:stress}$

Y = $\dfrac{\frac{F}{A}}{\frac{\delta\:L}{L}}$

Y = $\dfrac{FL}{A\:\delta\:L}$
