On gradual loading , stress - strain relationship for a metal wire is as follows . Within proportionality limit , stress prop strain or, "Stress"/"strain" = a constant for the material of wire. Just on crossing the yield region, the material will have

According to Hooke's law of elasticity, if stress is increased, the ratio of stress to strain

On gradual loading , stress - strain relationship for a metal wire is as follows . Within proportionality limit , stress prop strain or, "Stress"/"strain" = a constant for the material of wire. Two wires of same material have length and radius (L,r) and (2L , r/2) . The ratio of their young's modulii is
