A lever is used to lift a load of 600 N. The effort acts at a perpendicular distance of 0.75 m from the pivot. A resisting moment of 15 N m acts in the same direction as the load’s moment. The maximum effort is 100 N. What is the greatest perpendicular distance of the load from the pivot at which it can be held in rotational equilibrium?

0.15 m0.15\ \mathrm{m}0.15 m
0.10 m0.10\ \mathrm{m}0.10 m
