Objectives
• Students are required to understand the principles of torsion testing, practice their
testing skills and interpreting the experimental results of the provided materials
when failed under torsion.
• To determine the maximum shearing stress, shear stress at proportional limit, shear
modulus or modulus of rigidity and relationships between torque and degree of
rotation of the tested materials.
• Students are able to differentiate the ability of materials such as cast iron and brass
to withstand torque prior to torsion failure. Analysis and interpretation of the test
parameters obtained should be carried out in relation to the failure nature of each
material.
• Students are capable of selecting materials for engineering applications associated
with torsion.
