Simple Machines & Work
Across
- 5. A nail or rod shaped piece with a spiral groove and slotted head designed to to be inserted in an object by rotating.
- 6. The force you put on the machine.
- 8. Represents the force that a specific object has as a result of the input force.
- 10. The rate which work is done or energy is being converted.
- 11. A flat supporting surface tilted at an angle, with one end higher than the other, used to raise or lower a load.
- 14. Using a force to move an object over a distance.
- 15. A machine that consists of more than one simple machine.
- 19. The force which an effort force has to overcome in order to do work on an object.
- 20. A lever in which the fulcrum or pivot point is located between the effort force and resistance.
- 21. The ratio of the force produced by a machine to the force applied to it, assessing the performance of a machine.
- 22. A wheel with a rim of that a cord or rope fits around.
Down
- 1. The fixed point that a lever moves on.
- 2. Mechanisms that use mechanical advantage to multiply force; it makes work easier.
- 3. A bar that pivots on a a fixed point or fulcrum.
- 4. The force applied at one point on the lever in order to move an object.
- 5. A lever in which the load is between the effort and the fulcrum.
- 7. The pivot point around which a lever is supported and turns.
- 9. A lever in which the force is between the load and the fulcrum.
- 12. The SI unit of work or energy, equal to the work done by a force of one newton acting through one meter.
- 13. A simple lifting machine that consist of a rope that unwinds from a wheel onto a shaft joined to the wheel.
- 16. The SI unit of power, equal to 1 joule per second.
- 17. The ratio of the energy delivered by a machine to the energy needed in operating the machine.
- 18. A piece of material that has a thick end and tapering to a thin end, that is used to drive between two objects or parts of a object to separate them.
