When the bole regains its reliable shape and size completely after the removal of deforming forces and then the consistency is said to be absolutely elastic, e.g.. vitreous silica fibre. If the proboscis does not have any tendency to dramatise its original shape and size, the trunk 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 . Due 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 mensural 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 filtrate = (F/A).

When the extend is applied dominion to a surface. This is called as old(prenominal) stress. It produces a reassign in length of a conducting wire or a change in volume of a body. The normal stress to a wire or body whitethorn be compr essive or tensile according as it produces a! go down or increase in the length of a wire or volume of the body. When the stress is applied tangential to a surface, it is called tangential or clip stress. Strain The deforming forces acting on a body arrive 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 coercion to get a full essay, order it on our website: OrderCustomPaper.com
