We started with levers and weights and tried to find the relationship between the distance from the fulcrum (pivot point) and the load (weight).
In the next lesson, students were provided the relationship
To balance the lever:
Lever arm A x Load A = Lever arm B x Load B
We recognised the need to review the maths behind using this formula.
We first solved the following by inspection and then using rearrangement and cancelling
The last example is the set out for the first problem on the Balancing levers worksheet
