hi guys i have a sheet of i have the W,L and T a force and also the elastic modules etc

now my issue is i need to find the strain i have the stress etc but the is no extension figure given i have the usual strain equation e=x/l

can anyone point me in the right direction in regards to the equation [/B]

## Homework Equations

e=x/l

strain= stress/e

## The Attempt at a Solution

if my stress is 160 mpa and my gpa is 71 am i correct in strain = stress/e

160*10 to the power of 6/71*10 to the power of 9 =2.25 *10 to the power -2[/B]
