Materials
in Torsion
Abstract
Materials in human-powered vehicles are not only subjected
to simple tension or compression loads, but in many components torsional
loading also occurs . The response of a component to these torsional loads
depends upon a material property called the shear modulus, and the geometry
of the component through its geometric moment of inertia. In these experiments,
rods and tubes of different materials will be subjected to a torque and
their torsional deflection measured using an optical lever technique. Torsional
stress-strain curves will be plotted. The effect of sample geometry on the
response of the component will be compared to theoretical models. |
