Consider two wheels on the same shaft. One wheel has a large radius and the other wheel has a much smaller radius. By winding ropes around each wheel, we can use the large wheel to lift a very heavy load that is attached to the smaller wheel. See this image: https://s14.postimg.org/wzukfdxtd/wheellever.jpg Is this a lever? The same equation, W = F*s, can be applied here to understand how a small force can easily lift a very heavy load.
