Introduction:
In this lab we will investigate the relationships between the torque and angle of twist in different
materials. Having an understanding of these properties is important for designing and analyzing
components like shafts, gears, and other mechanical structures, where torque-induced rotational
deformation is a critical consideration. The objective of this lab is to measure and analyze the
relationship between the applied torque and the corresponding angle of twist. We utilize a torsional
testing setup to systematically apply a steady varying torque level to the specimen and measure the
angle of twist relative to the torque until the specimen ultimately fails. These tests will help us
understand the fundamental differences in materials and some of the reasons in which we should use on
material over the other.
