stiffness

Resistance to bending

Stiffness is the quality of being rigid or inflexible.

Physical stiffness refers to materials that resist bending or bodies that move with difficulty: the stiffness of new leather, morning stiffness in my joints.

Stiffness in manner suggests formality or unfriendliness: There was a stiffness between them after the argument.

In engineering, stiffness measures resistance to deformation under load.
