Lever principle and Equilibrium

This is my entry for the MakerEd Project Challenge. I am currently studying to became a vocational training teacher and I thought this challenge could help me thinking about simpler ways to explain enginnering concepts to my future students.

In this case I've created a model to explain how levers work and how you can reach the balance applying an opposite torque but taking into account weights and distances.

It is quite a simple concept for those who are used to it but not so if we are talking about young students.

With this project I want to help students understanding those concepts of torque (distance x weight), lever and equilibrium. Discovery learning can be used to learn those concepts!
