When the bole regains its authoritative shape and size completely after the removal of deforming forces thus the consistency is said to be utterly elastic, e.g.. vitreous silicon dioxide fibre. If the corpse does not have any tendency to become its original shape and size, the be is said to be perfectly plastic, e.g., plasticine. Stress When outside forces are exerted on a body, the body gets distorted, i.e., different portions of the body move sexual relation to apiece other. D ue to these displacements atomic forc es (restoring forces) are set up privileged the body to restore the original form. The restoring force per unit of measurement area set up inside the body is called emphasize. This is mensurable by the magnitude of deforming force per unit area of the body. If F is the force applied to an area of cross-section A, then latent hostility = (F/A).

When the emphasize is applied dominion to a surface. This is called as well-known(prenominal) stress. It produces a metamorphose in length of a conducting wire or a change in pile of a body. The normal stress to a wire or body whitethorn be compressive or tensile according as it produces a go down or increase in the length of a wire or volume o! f the body. When the stress is applied tangential to a surface, it is called tangential or snip stress. Strain The deforming forces acting on a body cause a relative displacement of its different parts and the body is then said to be strained. Either a change in length or a change, in volume or change in shape occurs. The relative change produced in the body due to the influence of external forces...If you exigency to get a full essay, order it on our website: OrderEssay.net
