Compression Test should require a higher capacity testing machine, because of the following reasons, During compression, there is decrease in length, and increase in diameter. So more load has to be applied to generate the same stress compared to Tensile test specimen of same original size, because in Tensile test, there…

When we pull any object, strain is induced in it due to stress generated, and so our efforts are stored into the object in the form of strain energy. When we pull the object very slowly, during plastic deformation, this strain energy will be disicipated into heat loss and gets diffused in the object, increasing the temperature.…
