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