Answer 1
When a material is applied a force on, stress develops on the material. This in turn leads to the deformation of the material. Engineering strain can be defined as the measure of deformation of the element in the direction of the applied force divided by the original length of the material. If the stress is lesser in amount, the material will only deform upto a very small measure and it will come back to its actual size after the loading is removed. In terms of engineering stress and strain parameters, we make the use of undeformed and actual cross sectional area of ...
