A structural steel rod has a radius r(=10 mm) and a length l(=1 m). When a force F(= 100 kN) is applied, it stretches it along its length. Young's modulus of elasticity of the structural steel is `2.0xx10^(11) Nm^(-2)`.
What is the stress produced ?

A

`1.59xx10^(9)Pa`

B

`.18xx10^(9)Pa`

C

`3.18xx10^(8)Pa`

D

`1.59xx10^(8)Pa`

Text Solution
