Which Material? 1

In this activity, from the Institution of Engineering and Technology (IET), students carry out some data analysis to find the best material from which to make a prosthetic foot. They plot graphs of stress against strain and calculate the modulus of elasticity for a number of candidate materials. The activity offers strong opportunities for cross-curricular work with mathematics.

Suggested learning outcomes include:

* Be able to make the link between material properties and material usage

* Understand how smart materials are used in a real life context

* Use and manipulate material-related data

This activity is a part of a full set of resources in the Nature Reinvented collection and is supported by the videos Nature Reinvented and Bionic Limbs.

Curriculum links include prosthetics, smart materials, stress, strain, elasticity, standard form, dimensions, gradient, measurements.
