A wedge and a inclined plane
Screw
Levers (the two blades) and wedges (the blade edges).
No. Gears are a type of simple machine. Combined with another simple machine, it would then make a compound machine.
There are six simple machines: Inclined Plane Wedge Screw Pulley Wheel Lever The two classes of simple machines are: 1. The simple machines that deal with vector quantities like velocity and force (the inclined plane, the wedge and the screw). 2. The simple machines that deal with torque (the force to rotate an object around an axis, pivot, etc.) like the pulley, the wheel, the lever. You would think a screw falls into the torque class, but it's classified as a helical inclined plane.
The two reasons why people use simple machines are because they make things easier to pull and lift.
The scissor style jack contains only two simple machines: the screw and the lever.

simple machines mean how work is being made easiersimple machines are pulleys levers lifts screws wedges wheels i might of covered all them or there might be one or two more
A screw is a combination of two simple machines: A wheel (the screw rotates about its axis) and an inclined plane (the thread of the screw) It is also used when the experiment goes wrong. ("Screw this, I'm going home")
A wedge and lever
The lever and the wedge.
