 | | For an anisotropic solid such as wood or paper, these three moduli do not contain enough information to describe its behaviour, and one must use the full generalized Hooke's law. |
 | | Piece of paper Paper is a thin, flat material produced by the compression of fibers (or fibres). |
 | | In physics, Hookes law of elasticity is an approximation which states that if a spring is elongated by some distance, x, the restoring force exherted by the spring, F, is proportional to x by a constant factor, k. |
