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
Within the elastic limit, the ratio of shear stress and shearing strain is called
The stress versus strain graphs for wires of two materials A and B are as shown in the figure. If YA and YB are the Young's moduli of the materials then
Will the stress and strain in all wires be the same?
