In this learning episode from the Institute of Physics, students use Hooke's law to demonstrate the strength and stiffness of materials when subject to linear tensile or compressive forces.

The activities include:
• recap of Hooke's law
• explaining tension and extension in a variety of materials
• explaining stiffness and elasticity
• investigating how the extension of a fibre varies with tension
• finding the breaking strength of fibres
