$\huge{\underline{\mathfrak{Question:- }}}$

A copper wire of 1mm diameter is stretched by applying a force on 10n. find the stress in the wire.

$\huge{\underline{\mathfrak{Answer:- }}}$

༈Given,

Diameter, d = 1 mm

Force, F = 10 N

༈Radius, r = $\frac{Diameter}{2}$

= $\frac{10}{2}$

$\huge{\underline{\mathfrak{To\:Find:- }}}$

Stress = ❔

$\huge{\underline{\mathfrak{We\:Know, }}}$

∴ Stress = $\frac{F}{A}$

⠀⠀⠀⠀= $\frac{F}{Πr^2}$

⠀⠀⠀⠀= 1.273 × 10^710
