A balanced lever has two weights on it, the first with mass #8 kg # and the second with mass #35 kg#. If the first weight is # 5 m# from the fulcrum, how far is the second weight from the fulcrum?
It is at a distance of
For a balance lever moments of the two forces must be equal. Moment is given by the product of weight and its distance from fulcrum.
Moment of first weight is
it is at a distance of
