Lever is an example of a machine that increases force.
Step-by-step explanation:
Lever, a simple machine comprises load, fulcrum and force. A load is an object that is moved or lift up. The fulcrum represents the support, and the effort looks as the force needed to lift or shift the load. Applying force at lever's one end (force applied) creates force at the lever's other end.
The applied force is increased or decreased depending on the distance from the support point (point or pillar on which the lever oscillates) to the load and from the fulcrum point to the force.
In general, simple machine that raises force is Lever. A simple machine, which has a bar, and pivoting on a fixed support, used for torque, is Lever. On a bar, one side of a lever is pushed down, to get the other side move up.
