Across
  1. 4. This simple machine is a rigid bar that pivots on a fulcrum
  2. 5. Ramps are this type of simple machine (two words)
  3. 9. Sprockets are connected by these, which cannot slip due to the teeth on the sprocket
  4. 10. The speed and direction in RPMs (ω) (two words)
  5. 11. This tells how well a machine works compared to how well it should work (AMA/IMA)
  6. 14. When two or more gears are meshed together, it is called this (two words)
  7. 15. This type of machine is made from two or more simple machines and the IMA is found by multiplying all the IMAs together
  8. 16. This type of mechanical advantage is based on forces, and is how well a machine DOES work (it's the A in AMA)
  9. 17. Meshed gears rotate in _____ directions
  10. 19. Rotational force (τ)
  11. 20. Pulleys, Levers, and Wedges are three examples of these (two words)\
Down
  1. 1. Simple machines give _____ _____, which alter force and distance, typically making something easier at the expense of longer distance
  2. 2. An axe head is the most common example of this type of simple machine
  3. 3. In this type of simple machine, mechanical advantage is determined by counting the number of effort strands
  4. 6. This simple machine has low efficiency, but high mechanical advantage
  5. 7. Doorknobs, water valves, and volume dials are all examples of this simple machine (three words)
  6. 8. This type of mechanical advantage is based only on distances, and is how well a machine SHOULD work (it's the I in IMA)
  7. 12. The size of a pulley is identified by its ____ since it doesn't have teeth (d)
  8. 13. Pulleys are connected by these, which can slip
  9. 14. The ____ ratio can be found by comparing the output diameter of a gear to the input diameter
  10. 18. The ____ on a gear allow it to interlock with other gears (n)
