Define stress. When an external force acts on a body, it undergoes deformation. At the same time the body resists deformation. The magnitude of the resisting force is numerically equal to the applied force. This internal resisting force per unit area is called stress. Define strain When a body is subjected to an external force, there is some change of dimension in the body. It states that when a material is loaded, within its elastic limit, the stress is directly proportional to the strain.
Define tensile stress and tensile strain. The stress induced in a body, when subjected to two equal and opposite pulls, as a result of which there is an increase in length, is known as tensile stress. The ratio of increase in length to the original length is known as tensile strain. Define compressive stress and compressive strain. The stress induced in a body, when subjected to two equal and opposite pushes, as a result of which there is a decrease in length, is known as compressive stress. The ratio of increase in length to the original length is known as compressive strain. Define shear stress and shear strain.

You all must have this kind of questions in your mind. Below article will solve this puzzle of yours. Just take a look.
Strain is defined as the ratio of a change in volume to original volume b change in length to original length c change in cross-sectional area to original cross-sectional area d any one of the above e none of the above. Ans: d. Ans: b. Ans: c. Deformation per unit length in the direction of force is known as a strain b lateral strain c linear strain d linear stress e unit strain. It equal and opposite forces applied to a body tend to elongate it, the stress so produced is called a internal resistanpe b tensile stress c transverse stress d compressive stress e working stress. The materials having same elastic properties in all directions are called a ideal materials b uniform materials c isotropic materials d paractical materials e elastic materials.
Я должен доставить эти вещи. На лице лейтенанта появилось оскорбленное выражение, какое бывает только у испанцев. - Вы хотите сказать, что даже не познакомитесь с Севильей. - Я был здесь несколько лет. Замечательный город.
