1.	a lever used to lift heavy box as an effort arm of 4m and a load arm of 0.8 meter what is the mechnical advantage of the lever?
Answer» MECHANICAL advantage is that...Explanation:it will INCREASE the torque of lifting even if we APPLY less force..torque =ř×fso more we increase the distance from the lifting....more it will get easier to lift the BOX even with comparatively less force.
