The ratio stress/strain remains constant for small deformation. What will be the effect on this ratio when the deformation made is very large?

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

The ratio of lateral strain to the longitudinal strain of a wire is called

The ratio of tensile stress to the longitudinal strain is defined as

Number of employees in a factory decreases in the ratio of 8 : 7 and salary of employees increases in the ratio of 5:6. Find wheather the total salary given to the empolyees is increased or decreased and in what ratio?

Number of employees in a factory decreases in the ratio of 8:7 and salary of employees increase in the ratio of 5:6 . Find whether the total salary given to the employees is increased or decreased and in what ratio ?

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
