Determining the stress-strain diagram governing the behavior of the material from which the mechanical properties of the material under test can be extracted. These properties are mainly represented by the modulus of elasticity E, Poisson’s ratio ν, percentage of elongation, modulii of resilience and toughness, yielding, ultimate and fracture or rupture strengths. Performing a twist or torque experiment to obtain/sketch the behavior of the material under test due to shear forces represented by the applied torque, and to determine modulus of rigidity G of the material.
