Simple Machines

5. is a simple machine consisting of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transferred from one to the other.
8. also known as a ramp, is a flat supporting surface tilted at an angle from the vertical direction, with one end higher than the other, used as an aid for raising or lowering a load.
10. a rod or spindle (either fixed or rotating) passing through the center of a wheel or group of wheels.
11. a circular object that revolves on an axle and is fixed below a vehicle or other object to enable it to move easily over the ground.

1. A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them.
2. A beam is a structural element that primarily resists loads applied laterally to the beam's axis (an element designed to carry primarily axial load would be a strut or column).
3. The support about which a lever pivots.
4. a beam or rigid rod pivoted at a fixed hinge, or fulcrum.
6. A screw is a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force.
7. A wedge is a triangular shaped tool, and is a portable inclined plane, and one of the six simple machines.
9. is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt.
