25 Questions

1. Pneumatic system in your body

2. The relationship between the speed of rotations of a smaller gear and a larger gear - can be calculated by dividing the number of driver gear teeth by the number of follower gear teeth.

3. F x d

4. Hydraulic system in your body

5. Distance between the fulcrum and the effort force

6. 1st class - 2nd class - 3rd class

7. Heated water to make steam and then used to move a piston. When the piston moved - it caused an attached rod (which was connected to a crankshaft) to move as well - making the engine work.

8. The production of large quantities of a standardized article (often using assembly line techniques)

9. Do not seal the gas (usually air)

10. To increase the force on the output piston - the input piston must move through a greater distance

11. A measure of the amount of force applied to a given area

12. Required a large shift in population from rural areas to the cities.

13. Do the work faster

14. Unit of measurement for pressure

15. (driven gear) smaller gear

16. Use the force of a liquid in a confined space - apply two essential characteristic of fluids - their incompressibility and their ability to transmit pressure

17. Or ramp - makes it easier to move a load higher than it is - but - it has to be moved over a much longer distance.

18. A rigid bar or plank that can rotate around a fixed point

19. Do the work easier

20. Is the work needed to use - or operate the machine

21. Act like levers

22. Is the work done by the machine

23. Force exerted on the lever to make it move

24. Force of the small piston/area of the small piston = Force of the large piston/Area of the large piston

25. Used to control the flow of a fluid. It is a moveable part that controls the flow by opening or closing
