A balanced lever has two weights on it, the first with mass #14 kg # and the second with mass #9 kg#. If the first weight is # 2 m# from the fulcrum, how far is the second weight from the fulcrum?
A moment is the product of force and the distance over which the force acts.
In a balanced lever, both moments are equal to each other, so
We can work out the force either side by
and put these values, along with
