👉 Rigidities are characteristics of a physical system that describe how it behaves under varying conditions. They can be characterized by their stiffness, elasticity, or moduli, which indicate how easily an object deforms or changes shape in response to external forces.
Examples of rigidities include:
-
Stiffness
: The resistance of an object to deform without changing its shape.
-
Elasticity
: The ability of a material to return to its original shape after being compressed or stretched.
-
Mod
