Aims
On completion of this TLP you should:
- know how to measure the Young's modulus of a material from the deflection of a cantilever beam made from the material
- understand the origin of the thermal expansion of a solid
- understand how the curvature of a bi-material strip is related to the stiffness of the materials from which it is made and the temperature change it undergoes
- be able to use this relationship to calculate temperature changes and linear expansivities
