Man uses some simple machines to make work easier. There are 6 simple machines and levers being one of the six. Levers are divided into 3 different classes according to the location of the fulcrum in relation to the weight and effort force. Using levers, man is able to gain speed, change in direction, or effort. Of course, man is more interested in gaining effort. In other words, move more weight with less effort.

In the second class lever,change of direction, nor speed can be gained,but only effort is gained again according to the location of the fulcrum. The third class the only thing gained is speed.
