Question

Is stone rigid or non-rigid?

Answer 1

Rigidity

A rigid body is defined as one that maintains its original shape even when subjected to external forces. No matter what external forces or moments are applied to a rigid body, the space between any two specified points remains constant in time.

Stone is rigid

The property shown by the solid varies in shape, and rigidity is specified. When an external force is applied to a solid substance, the shape does not change. This indicates that the particles are tightly packed, implying that the attraction between them is very strong.

Hence, Stone is rigid.
