Across
- 3. Also called parallel motion. The output travels in the same direction as the input. (4/4)
- 4. A rigid bar resting on a pivot, used to move a heavy or firmly fixed load with one end when pressure is applied to the other.
- 6. A circular motion. (6,6)
- 8. A shaped piece of metal or plastic fixed to a rotating shaft.
- 9. If an 'L'-shaped lever is pivoted at its centre, the direction of the input movement or force would be turned through 90° at the output. (4,5)
- 11. The great size or extent of something.
- 12. This type of leaver has the turning point (fulcrum) between the load and the effort. A well-known first order lever is the see-saw. (5,5)
- 13. Strength or energy as an attribute of physical action or movement.
Down
- 1. A wheel with a grooved rim around which a cord passes, which acts to change the direction of a force applied to the cord and is used to raise heavy weights.
- 2. This lever have the effort is between the load, at the top, and the fulcrum. (5,5)
- 4. Mechanisms which allow force or motion to be directed where it is needed.
- 5. The part of a machine in sliding or rolling contact with a rotating cam and given motion by it.
- 7. A lever that has the load between the fulcrum and the effort. (6,5)
- 10. A continuous band of material used in machinery for transferring motion from one wheel to another.
