Philip Harris Young's Modulus Apparatus
Philip Harris Young's Modulus Apparatus
Product code: HE1008261
Product Description
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
- AS Level Physics - Mechanics and Materials: The definition of Young Modulus, experiment to determine the Young modulus.
- Safety Goggles should be worn at all times.
- The ceiling bracket comes with two wood screws to secure the bracket to a convenient overhead beam or door frame. This is typically a permanent installation in the laboratory.
- The load on the wires should not exceed 2kg to reduce the risk of the wires breaking suddenly.
