SIMPLE MACHINES-THE LEVER.

WHENEVER a machine is used, it is intended to accomplish one or more of the three following purposes :—1. To direct the force which is put into action by the moving power. 2. To change the velocity of a force, and to produce one suited to the object required : or, 3. To assist or

The third class of levers is that in chanical arrangement may be discovered, with a little attention, if the principles of these be perfectly understood.

We might, therefore,
