I always thought there were seven simply because "Seven Simple Machines" sound familiar.

There are only 3 simple machines... the inclined plane the wheel & axle the lever Some people include others, such as... wedge (an inclined plane) pulley (just a wheel) screw (an inclined plane wrapped around an axle) gear (just a modified wheel) I suppose you can list specific instances. Axle Blade (an inclined plane) Can opener (church key style, a lever) Doorknob (wheel) Eggbeater (gear) Fire escape (usually has counterweighted pulleys) Golf club that should get you started!

1. Inclined Plane
2. Wheel and Axle
3. Lever
4. Pulley
5. Wedge (this is application of inclined plane)
6. Screw (this is application of inclined plane and wheel/axle)
Kind of depends on how nitpicky you want to be. I typically say the first four but some people say all six or even include hydraulics as a seventh.

6: the lever, the inclined plane, the pully, the wheel, the screw and the wedge.
This is the usual nomenclature, but when you look at them closely, the pully is a variation on the wheel; the screw is a combination of the wheel and the inclined plane.
