Given values:-

Elastic limit of steel i.e.

σ = 8 x10⁸ N/m²

Young modulus i.e.

Y =2.0 x10¹¹ N/m²

_______________________________________

SOLUTION:-

maximum stress in the wire

σ= 8 x10⁸ N/m²

Y =2.0 x10¹¹ N/m²

Let the Length of the wire:-

L =0.50 m

maximum elongation = l m

Strain ε= l/L

=l/0.50

=2l

Formulae :- σ/ε =Y

▶ε =σ/Y

▶2l = 8 x10⁸/2.0 x10¹¹

▶l =2/1000 m

= 2 mm

$ANSWER:- 2 mm$
