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)
