**Stiffness** is the rigidity of an object — the extent to which it resists deformation in response to an applied force. The complementary concept is **flexibility** or pliability: the more flexible an object is, the less stiff it is.

### Famous quotes containing the word stiffness:

“Everything ponderous, viscous, and solemnly clumsy, all long- winded and boring types of style are developed in profuse variety among Germans—forgive me the fact that even Goethe’s prose, in its mixture of *stiffness* and elegance, is no exception, being a reflection of the “good old time” to which it belongs, and a reflection of German taste at a time when there still was a “German taste”Ma rococo taste in moribus et artibus.”

—Friedrich Nietzsche (1844–1900)
