Hi all,
This is my first post in PF
I'm doing my ninth standard in India,My knowledge in physics is limited so please forgive me if I ask something basic
Can anyone clearly explain me the relationship stress and strain,because I thought when a material deforms (even to the slightest degree)restoring forces are set up to bring it back to original position (which is stress in elastic zone).
By when a bar constrained at both ends is heated,it cannot deform because it is fixed,whereas it is stresses(which violates what i said before because stress can occur only if there is strain).
Once again sorry if i have asked something very basic and thanks in advance.
