Stress & Strain

(A): Strain is a unitless quantity. (R): Strain is equivalent to force.

The ratio of shearing stress to the shearing strain is defined as

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. If "Stress"/"Strain" is x in elastic region and y in the region of yield , then

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
