According to Hooke’s law, within the elastic limit stress/strain = constant. This constant depends on the type of strain or the type of force acting. Tensile stress might result in compressional or elongative strain; however, a tangential stess can only cause a shearing strain. After crossing the elastic limit, the material undergoes elongation and beyond a stage beaks. All modulus of elastically are basically constants for the materials under stress.
Two wires of same material have length and radius (\(\ell\), r) and \(\left(2 \ell, \frac{\mathrm{r}}{2}\right) .\)The ratio of their Young’s modulus is
