The point on stress-strain curve at which strain begin to increase even without increase in stress is called

Strain energy of a stretched wire is $18\times {10}^{-3} \mathrm{J}$ and strain energy per unit volume of same wire and same cross section is $6\times {10}^{-3}$$\mathrm{J}/{\mathrm{m}}^3$.  Its volume will be

What is the property of a material that enables it to resist plastic deformation?

The ability of a material to resist fracturing when force is applied to it, is called

What do you mean by elastic hysteresis?

States the name of the hardest material and the softest material.

Define friction.

State Hooke’s law. Draw a labeled graph of tensile stress against tensile strain for a metal wire up to the breaking point. In this graph show the region in which Hooke’s law is obeyed.
