A copper wire of 1mm diameter is stret- ched by applying a forcre of 10 N. Find the stress in the wire.

Text Solution

Verified by Experts

Diameter, d=1mm
`therefore"radius,"r=0.5mmxx10^(-3)m`
`"Force,"F=10N`
`"Stress"=("Force")/("Area")=(F)/(pir^(2))`
`therefore"Stress"=(10)/(3.141xx0.5xx0.5xx10^(-6))`
`=(40xx10^(-6))/(3.141)=1.273xx1-^(7)"Pa"`
