Mechanical Systems

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • 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. The rate of motion that an object changes position






2. The ratio of the output to the input of any system - a comparison of the useful work provided by a machine or a system with - the work supplied to the machine or system






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






4. Distance between the fulcrum and the load






5. A fixed point






6. Do the work faster






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






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






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






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






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






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






13. Distance between the fulcrum and the effort force






14. Pneumatic system in your body






15. 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






16. 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.






17. F x d






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






19. Energy of motion






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






21. Unit of measurement for pressure






22. 1st class - 2nd class - 3rd class






23. 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.






24. (driven gear) smaller gear






25. Work unit






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






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






28. Is the work done by the machine






29. Mass of the object lifted by the lever






30. Do not seal the gas (usually air)






31. Stored energy






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






33. Do the work easier






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






35. 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)






36. The fluid transfers the pressure from the input piston to the ____________






37. Act like levers






38. Are used to overcome the frictional force of the machine






39. Pressure applied to an enclosed fluid is transmitted undiminished in all directions throughout the fluid and perpendicular to the walls of the container.

40. F/A






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






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






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






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






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






46. 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.






47. Hydraulic system in your body






48. Force exerted on the lever to make it move






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






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