Across
- 4. Two different sized circular objects that are attached together and turn as one.
- 5. A profession for which one trains and which is undertaken as a permanent calling.
- 6. A circular toothed object used to transfer rotary motion and torque through interlocking teeth.
- 7. An inclined plane wrapped around a cylinder, forming the path and pitch.
- 12. The ratio of the magnitude of the resistance and effort forces applied to a system.
- 13. Any of various elementary mechanisms including the lever, the wheel and axle, the pulley, the inclined plane, the wedge, and the screw.
- 15. The resistance that one surface or object encounters when moving over another.
- 18. The structure of or the relationship of the parts in a machine, or in a construction or process comparable to a machine.
- 19. A continuous band of tough flexible material used to transmit motion and power within a pulley system.
- 20. An external force applied to an object.
- 21. Plane A flat surface set at an angle or an incline with no moving parts that is able to lift objects by pushing or pulling the load.
- 22. The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force.
- 23. A series of usually metal links or rings connected to or fitted into one another and used to transmit motion and power within a sprocket system.
- 24. A type of lever that is a wheel with a groove in its rim, which is used to change the direction or multiply a force exerted by a rope or cable.
Down
- 1. A rigid bar used to exert a pressure or sustain a weight at one point of its length by the application of a force at a second and turning at a third on a fulcrum.
- 2. Ratio of distance traveled by the applied effort and resistance force within a system.
- 3. Gear A gear positioned between the driver and the driven gear used to change rotational direction.

- 9. The fixed point around which a lever rotates.
- 10. Impeding effect exerted by one material object on another.
- 11. A substance that tapers to a thin edge and is used for splitting, raising heavy bodies, or for tightening by being driven into something.
- 12. The recognized accreditor for college and university programs in applied science, computing, engineering, and technology.
- 14. A toothed wheel whose teeth engage the links of a chain.
- 16. A force that produces or tends to produce rotation or torsion.
- 17. The ratio of useful energy output to the total energy input, or the percentage of the work input that is converted to work output.
