Mechanical Systems

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes. 2 minutes extra for reading the instructions.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Pressure applied to an enclosed fluid is transmitted undiminished in all directions throughout the fluid and perpendicular to the walls of the container.


2. Within a machine are groups of parts that perform specific functions - such as braking or steering






3. F/A






4. Energy of motion






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






6. Do not seal the gas (usually air)






7. Distance between the fulcrum and the load






8. A small gear driving a larger gear increases torque and reduces speed in the driven gear






9. The combustion occurs inside the engine. The pistons goes through 4 steps: Intake stroke (taking in the fuel) - compression stroke (compressing the fuel- air mixture) - power stroke (the fuel- air mixture is ignited) - exhaust stroke (waste products






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






11. Stored energy






12. (driven gear) smaller gear






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






14. Pneumatic system in your body






15. A combination of two wheels of different diameters that turn together - a lever that rotates in a circle around a center point or fulcrum.






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






17. Science of designing machines to suit people






18. Distance between the fulcrum and the effort force






19. 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.






20. A very complex combination of pulleys - including fixed and movable is called






21. 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.






22. Force exerted on the lever to make it move






23. A fixed point






24. Act like levers






25. Consists of a small cylinder that has a crank or handle. The axle of the winch acts like the fulcrum - the handle is the effort arm






26. Do the work faster






27. Do the work easier






28. A large gear driving a smaller gear decreases torque and increases speed in the driven gear






29. 1st class - 2nd class - 3rd class






30. Work unit






31. F x d






32. Used to apply force to the fluid - which creates pressure in the fluid






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






34. A group of parts that work together to perform a function






35. Work done by machine / work done to make the machine operate x100






36. The comparison of the force produced by a machine to the force applied to the machine. (the size of the load vs the size of the force needed to move the load)






37. Transferred to kinetic energy in machines in a dam to generate electrical energy






38. Heated water to make steam and then used to move a piston in a circular motion






39. A pair of wheels that have teeth that interlink. When they rotate together - one gear wheel transfers turning motion and force to the other.






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






41. The rate of motion that an object changes position






42. Energy is transferred from one place to another - and no energy is changed or converted.






43. Load Force (FL)/Effort Force (FE)






44. Mass of the object lifted by the lever






45. Is done when a force acts on an object to make that object move - a transfer of energy






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






47. Bigger gear






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






49. Unit of measurement for pressure






50. Consists of a wire - rope - or cable moving on a grooved wheel. One or more combinations of wheels and ropes can be fixed in place or moveable - help you lift larger loads.
