If free to expand.
Change in length =ALPHA*TEMP*LENTH
If ends prevented
Strain=change in length/original length
So strain=Alpha * temp
Stress=youngs modulus (E)*strain
=E*alph*temp.
Change in length =ALPHA*TEMP*LENTH
If ends prevented
Strain=change in length/original length
So strain=Alpha * temp
Stress=youngs modulus (E)*strain
=E*alph*temp.

The thermal stress = alpha * TEMPERATURE * YOUNGS's Modulus.

@ Purvi.
I agree this for tapper rod.

It depends.
alpha. t.Ed1/d2.
