Across
  1. 2. a common unit of power equal to 746 watts, first based on the power output of a very strong horse
  2. 6. a V-shaped object with two sides that are two inclined planes sloped towards each other
  3. 7. the distance the input force is exerted over
  4. 9. two circular objects attached together about a common axis
  5. 10. the units for work
  6. 11. the number of times that the machine increases an input force
  7. 17. the work done by the output force over the output distance, the work that comes out of the machine
  8. 18. consists of a rope that fits into a groove in a wheel
  9. 19. an inclined plane wrapped around a cylinder
  10. 20. a device that changes a force, it makes work easier to do
  11. 21. the rate of getting work done
  12. 22. the actual forces acting on a machine, it equals the ratio of the output force to the input force
  13. 23. the distance the output force is exerted over
Down
  1. 1. the work done by the input force over the input distance, the work put into a machine
  2. 3. the mechanical advantage in the absence of friction
  3. 4. the force that is put out by a machine
  4. 5. a slanted surface along which a force moves an object to a different elevation
  5. 8. a rigid bar that pivots/turns around a fixed point (fulcrum)
  6. 12. the force put into a machine
  7. 13. the units for power
  8. 14. the percentage of work input that becomes work output, is always less than 100%
  9. 15. a combination of two or more simple machines that operate together
  10. 16. the product of force and distance, it is done when a force acts on an object in the direction the object moves
