Mechanisms - Key Terms
Across
- 1. A continuous band of tough flexible material used to transmit motion and power within a pulley system
- 3. An inclined plane wrapped around a cylinder, forming the path and pitch
- 6. The resistance that one surface or object encounters when moving over another
- 10. A profession for which one trains and which is undertaken as a long-term vocation
- 12. A circular toothed object used to transfer rotary motion and torque through interlocking teeth
- 13. 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
- 17. Ratio of distance traveled by the applied effort and resistance force within a system
- 18. A force that produces or tends to produce rotation or torsion
- 21. The structure of or the relationship of the parts in a machine or in a construction or process comparable to a machine
- 24. 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
- 25. The recognized accreditor for college and university programs in applied science, computing, engineering, and technology
- 26. The ratio of useful energy output to the total energy input, or the percentage of work input that is converted to work output
- 27. 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
Down
- 2. Creating, designing, and transmitting technical information so that people can understand it easily and use it safely, effectively, and efficiently
- 4. The ratio of the magnitude of the resistance and effort forces applied to a system
- 5. Distance between adjacent threads in a screw
- 7. An external force applied to an object
- 8. Any of various elementary mechanisms including the lever, wheel and axle, pulley, inclined plane, wedge, and screw
- 9. A gear positioned between the driver and the driven gear used to change rotational direction
- 11. Two differently sized circular objects that are attached together and turn as one
- 14. The fixed point around which a lever rotates
- 15. 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
- 16. Impeding effect exerted by one material object on another
- 19. A substance that tapers to a thin edge and is used for splitting, raising heavy bodies, or tightening by being driven into something
- 20. 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
- 22. A toothed wheel whose teeth engage the links of a chain
- 23. 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
