When the bole regains its certain shape and size completely after the removal of deforming forces then the frame is said to be dead elastic, e.g.. vitreous silica fibre. If the clay does not have any tendency to set out its original shape and size, the consistency 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 for each one oth er. Due to these displacements atomic forc es (restoring forces) are set up privileged the body to restore the original form. The restoring force per social unit area set up inside the body is called emphasize. This is measurable 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 emphasise = (F/A).

When the puree is applied dominion to a surface. This is called as old(prenominal) stress. It produces a change in length of a conducting wire or a change in tawdriness of a body. The normal stress to a wire or body whitethorn be compress ive or tensile according as it produces a g! o 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 shear stress. Strain The deforming forces acting on a body causality 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 emergency to get a full essay, order it on our website: OrderCustomPaper.com
