A balanced lever has two weights on it, the first with mass #6 kg # and the second with mass #7 kg#. If the first weight is # 5 m# from the fulcrum, how far is the second weight from the fulcrum?

Answer:

The distance is #=4.28m#

Explanation:

enter image source here

The load #L=6gN#

The distance of the load from the fulcrum is #=5m#

The effort is #E=7gN#

The distance of the effort to the fulcrum is #xm#

In a situation of equilibrium, the moments are equal

So,

#6*5=7*x#

#x=30/7=4.28m#
