Data Sheet

Aluminium rod diameter $=6\mathrm{.}35mm$

Aluminium rod length $=295mm$

Pulley Diameter $=180\mathrm{.}2mm$

Length of lever $=34mm$

Using the given pulley radius and the weight values, calculate the torque applied to the

specimens.

$2$ Calculate the theoretical angle of twist.

Calculate the experimental angle of iwist for the specimen by using the dial gauge readings

and the lever distance to where the dial gauge makes contact.

Calculate the maximum torsional shear stress and compare the values to the shear stress

limits of the material and discuss.
