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