Modulus of Rigidity Apparatus and Diagram
Description
The apparatus consists of a rod clamped at one end and attached to a wheel at the other. The rod passes through a bearing at the wheel end and known torques may be applied by a string wrapped around the wheel. The twist in the rod is measured with an angular scale.
