Hi.. I need a good explanation for the following question. an explanation with a small mathematical calculation to prove the answer would be highly helpful.
A copper rod of cross-section 10 mm 10 mm is stretched along its axis, changing length from 1.000 m to 1.001 m. The deformation is elastic, or fully recoverable. Given that the modulus of copper is 110 GPa, the stress on the rod is approximately (choose the closest answer):
A 110 kPa
B 110 MPa
C 110 GPa
D 1/110 MPa
E 1/110 GPa
thanks in advance!
