Question

What do we understand by plasticity of metals?

• A. Temporary deformation without breaking or rupturing
• B. Permanent deformation without breaking or rupturing
• C. Temporary deformation only till pressure lasts
• D. None of the choices

Answer 1

The correct option is B

Permanent deformation without breaking or rupturing

The plasticity is nothing but the ability of a metal to withstand severe permanent deformation without breaking or rupturing.

In other words, it is the deformation of a material undergoing non-reversible changes of shape in response to applied forces.
