Mechanical Systems 2

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. A system in which a gas - such as air - transmits a force exerted on gas in an enclosed space.






2. A rotating gear that meshes with a bar that has gear teeth along its length. Changes rotating motion into linear motion.






3. A device used to regulate the flow of a liquid in a hydraulic system.






4. A threaded shaft used to convert rotary movement to linear movement.






5. The science of designing gone or work environments that best suit the human body in it various dimensions.






6. The transmission of power between shafts by means of a belt connecting pulleys on the shafts.






7. A lever in which the effort is applied between the fulcrum and the load.






8. A machine used for raising or moving liquids.






9. The ability to do work.






10. Movement in a straight line.






11. The work done by a machine as the output force acts through the output distance






12. The quantitative relation between two amounts showing the number of times one value contains or is contained within the other.






13. A small cogwheel that engages or is engaged by a larger cogwheel.






14. The ratio of the force produced by a machine or system (the load) to the force applied to the machine or system.






15. A push or pull on an object.






16. Circular movement.






17. A gear with teeth that fits into the links of a chain.






18. A wheel with a grooved rim to guide a rope or chain that runs along the groove; used to transmit or change direction of force.






19. The application of force that moves an object a certain distance.






20. A lever in which the load is between the fulcrum and the effort.






21. A law stating that when pressuer is exerted on on part of a fluid - the same pressure is transmitted unchanged to all parts of the fluid - no matter what the shape of the container holding fluid. EX: water balloon.

25. The distance between adjacent threads in a screw.






26. Something put into a system - such as resources - in order to achieve a result.






27. The force acting perpendicular to a certain surface area.






28. A joint that allows connected shafts to spin freely while permitting a change in direction.






29. A way to measure stuff.






30. The that has a handle because of a motoe or person turning it.






31. The gear which transmits power and motion to the rest of the system. The input gear.






32. A gear between the driver and the driven gear used to change rotational direction.






33. Opposite in position - direction - order or effect.






34. A lever in which the fulcrum is between the effort and load.






35. The part of a machine which contains two or more pieces arranged so that the motion of one compels the motion of the others.






36. The ratio of the useful work or energy provided by a machine or system with the actual work or energy supplied to the machine or system.






37. The member of a pair of gears to which motion and power are transmitted by the other. The output gear.






38. The gear being turned buy the driver gear






39. A secondary or subordinate system that is part if a larger system.






40. A mechanical system that uses a liquid under pressure in a close system to raise heavy objects.






41. A rotating wheel- like device with teeth around the rim.






42. The weight of an object that is is moved or lifted by a machine - or resistance to movement that a machine must overcome






43. The results of the operation of any system.






44. A combo of several pulleys working together.






45. A system having a boundary that separates it from it surroundings.






46. The distance in a strait line from the center of a circle to the circle circumference






47. A pear- shaped disk with an off- center pivot point - used to change rotating motion into reciprocating motion.
