- 4. simple machine that consists of a cylinder with a groove cut in a spiral on the outside
- 10. simple machine made up of a flat surface, such as a board, at an angle to to another flat surface, such as the ground or a table top
- 11. simple machine made up of a ridge bar or plank that rotates on a fixed object called a pivot or fulcrum
- 13. belt or chain to transfer energy from an energy source to an object
- 14. system that uses a liquid under pressure to move loads

- 20. purpose or task
- 21. measurement of how well a machine or device uses energy
- 24. a plan or drawing produced to show the look and function or workings of a building, garment, or other object before it is built or made
Down
- 1. simple machine that looks like an inclined plane, but if forced into an object
- 2. fulcrum in the middle, the effort is applied on one side of the fulcrum and the resistance (or load) on the other side
- 5. system in which simple machines all work together
- 6. simple machine made up of two wheels of different diameters that turn together
- 7. when pressure is applied to a liquid in a container, the pressure and force is transmitted equally and undiminished throughout the liquid
- 8. force a machine applies to an object
- 9. device that helps us do work

- 15. measure of the amount of force applied to a given area
- 17. force applied to operate a machine
- 22. force that opposes
- 23. (in context of machine) a group of parts that work together to perform a general function, forming a complex machine
