The Young’s modulus of a material describes how it behaves under a load. It is defined as the ratio of stress to strain.  Stress is force per unit area; or pressure; measured in Pa; and strain is a ratio of lengths; so has no units. Therefore; Young’s modulus is a measure of pres...

To determine the value of 'g' by timing the fall of a steel ball.

The release unit consists of a plate (90mm x 45mm x 3mm) carrying a pair of metal clips connected to 4mm sockets. The clips are opened; thus dropping the ball and breaking the contact between the clips.

The trip unit is...
