Across
  1. 3. the point in which the lever rests
  2. 4. smaller groups of parts within a complex machine that performs a specific function
  3. 7. measurment of how well a machine or device uses energy
  4. 9. simple machine made up of a a wire, rope, or cable moving on a groove wheel; may be made up of one or many wheels; can be fixed in place or moveable
  5. 10. amount by which a machine can multiply a force; calculated by dividing the output force by the input force
  6. 12. measurement of the amount of force applied to a given area
  7. 13. force applied to operate a machine
  8. 15. a group of parts that work together to perform a general function, forming a complex machine
  9. 17. a plan or drawing produced to show the function or workings of a machine
  10. 19. simple machine made up of a flat surface, such as a board, at an angle to another flat surface, such as the ground or a table top; ramp
  11. 20. simple machine made up of two wheels of different diameters that turn together; a longer motion on the wheel produces a shorter but more powerful motion at the axle
  12. 21. of wheels with teeth that interlink; when they rotate together, one gearwheel transfers turing motion and force to the other
  13. 23. simple machine that looks like an inclined plane, but is forced into an object
Down
  1. 1. force a machine applies to an object
  2. 2. special type of linkage for transffering the energy from the engine to the wheels in large vehicles such as cars and trucks
  3. 3. purpose or task
  4. 5. simple machine that consists of a cylinder with a groove cut in a spiral on the outside
  5. 6. system that uses liquid under pressure to move loads
  6. 8. measures of how the speed of the object is affected by a machine
  7. 10. device that helps us do work
  8. 11. force that opposes motion
  9. 14. tool or device made up of one basic machine
  10. 16. when pressure is applied to a liquid in a container, the pressure and force is transmitted equally and undiminished throughout the liquid
  11. 18. belt or chain to transfer energy from an energy source to an object
  12. 22. simple machine made up of a rigid bar or plank that rotates on a fixed object called a pivot or fulcrum
