Lardner Hand-bk. Mech. (1858) ii. iii. 76 If the elasticity of the body be imperfect, then the restoring force will have less intensity than the compressing force. 1900 Science 27 Apr. 664/2 The amplitude of the vibration became so great that the restoring force was no longer proportional to the displacement. 1995 P.
