A balanced lever has two weights on it, the first with mass #6 kg # and the second with mass #45 kg#. If the first weight is # 9 m# from the fulcrum, how far is the second weight from the fulcrum?
A body which has no tendency to rotate under the combined result of a number of forces acting on it is called to be a balanced state.
The rotational tendency of a force is called Moment of the force.
Also in a balanced lever clockwise moments are equal to clockwise moments.
In the given question, forces acting are two weights for which
