Across
- 3. 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 point and turning at a third on a fulcrum.
- 7. 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.
- 8. An external force applied to an object.
- 10. The fixed point around which a lever rotates.
- 11. A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.
- 12. The resistance that one surface or object encounters when moving over another.
- 15. 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.
- 18. Any of various elementary mechanisms including the lever, wheel and axle, pulley, inclined plane, wedge, and screw.
- 19. A substance that tapers to a thin edge and is used for splitting, raising heavy bodies, or tightening by being driven into something.
- 23. The ratio of the magnitude of the resistance and effort forces applied to a system.
- 24. The ratio of useful energy output to the total energy input, or the percentage of work input that is converted to work output.
- 25. 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.
- 26. A gear positioned between the driver and the driven gear used to change rotational direction.
Down
- 1. Ratio of distance traveled by the applied effort and resistance force within a system.
- 2. A toothed wheel whose teeth engage the links of a chain.
- 4. A profession for which one trains and which is undertaken as a long-term vocation.
- 5. Creating, designing, and transmitting technical information so that people can understand it easily and use it safely, effectively, and efficiently.
- 6. A force that produces or tends to produce rotation or torsion.
- 9. Impeding effect exerted by one material object on another.
- 13. A continuous band of tough flexible material used to transmit motion and power within a pulley system.
- 14. Two differently sized circular objects that are attached together and turn as one.
- 16. Distance between adjacent threads in a screw.
- 17. An inclined plane wrapped around a cylinder, forming the path and pitch.
- 20. The structure of or the relationship of the parts in a machine or in a construction or process comparable to a machine.
- 21. A flat surface set at an angle (or incline) with no moving parts that is able to lift objects by pushing or pulling the load.
- 22. The recognized accreditor for college and university programs in applied science, computing, engineering, and technology.
- 27. A circular toothed object used to transfer rotary motion and torque through interlocking teeth.
