Practical - Young Modulus

Two methods that can be used to find this material property - sometimes called Young's modulus.

 

1. The Young Modulus of Copper

This is a straight-forward way to measure the Young's Modulus of a material. Copper wire is often used as it is stretched by weights hung over the edge of the bench, with the small extension carefully measured with a ruler.

Wear eye protection in-case the wire snaps.

 

1. The Young Modulus of Steel (with a Vernier Scale)

This is a great way to measure the Young's Modulus if you have the equipment at your school. Steel wire does not extend much so the small extension is measured using a vernier scale.

Wear eye protection in-case the wire snaps.
