Non-linear extension and plastic. Area under graph 05Fx This area is the energy stored in the spring. Force-extension graphs Linear extension and elastic deformation can be seen below the limit of proportionality.
So its area is one half times its height times its base.
B Calculate the stress required to create a neck in the sample in MPa. This area can be calculated. So its area is one half times its height times its base. Work done to deform an object is referred to as strain energy.
