In engineering, deformation refers to the change in size or shape of an object. Displacements are the absolute change in position of a point on the object. Deflection is the relative change in external displacements on an object. Strain is the relative internal change in shape of an infinitesimally small cube of material and can be expressed as a non-dimensional change in length or angle of distortion of the cube. Strains are related to the forces acting on the cube, whi… Web1) As an object is stretched its area reduces so shouldn't the stress developed increment (like integrating the small increments for a small decrease in area == total tensile stress)? …
