ABSTRACT
This experiment highlights the procedure to determine such properties as modulus of elasticity in shear and the torsion yield strength. During the experiment, aluminium and mild steel was used to demonstrate how the materials behave during the testing condition. By measuring the applied torque with respect to the angle of twist, the Torsional rigidity (GJ), the Modulus of Rigidity (G) and the shear yield stress (τ) for ductile materials, mild steel and aluminium.
INTRODUCTION
The purpose of this experiment is to study and to compare the behaviour of ductile and brittle materials under torsion. This experiment is done using the torsion testing machine. The torsion apparatus used in this experiment has a diameter of 6mm with hexagonal ends. This experiment also serves to calculate the Torsional rigidity (GJ), the Modulus of Rigidity (G) and the shear yield stress (τ) for ductile materials, mild steel and aluminium. The modulus of rigid (G) serves as the ultimate goal, can be found by
G = T.lJ∅ , where T is the applied torque (N.m),l is
