YOUNGS MODULUS APPARATUS
If you want to purchase this product or view prices you will need to have an account.
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 pressure and has sI units of Pa.
Comprises a scale plate carrying a 0 to 30mm scale, and a moveable vernier readable to 0.1mm. Both have bars with clamping screws for the wires and hooks for the tension weight and loading masses. A ceiling clamp is provided for the upper ends of the wires, together with a pair of large wood screws for attaching it to a convenient overhead beam, door frame etc.
A tension weight, mass 1.3kg approx., for the comparison wire is also included.
- supplied WITHOUT load masses or wires.
In addition to the apparatus, the following items are required:
- set of wires (a mixed set is available to purchase separately)
- screw Gauge Micrometer (B8R06348)
- slotted 100g masses (B8A73088)
- safety Goggles
