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 pulley supported by attachment to something that does not move - such as a ceiling - wall - or tree.






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






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






4. A twisting force.






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






6. 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.






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






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






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






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






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






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






13. A way to measure stuff.






14. 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.






15. The work done on a machine as the input force acts through the input distance






16. Circular movement.






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






18. Movement in a straight line.






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






20. Measurement for work






21. Work= force x distance






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






23. The gear being turned buy the driver gear






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






25. The ability to do work.






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






27. A mechanical arrangement consisting of a toothed wheel driven by a short revolving cylinder bearing a screw thread.






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






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






30. A combination of fixed and movable pulleys - may be used to list very heavy or awkward loads.






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






32. A back and forth movement.






33. Energy is transferred from one plan to another - and no energy is changed or converted.






34. The results of the operation of any system.






35. A combination of two or more gears used to transmit motion between two rotating shafts or between a shaft and a slide.






36. A machine used for raising or moving liquids.






37. The point of the lever that does not move.






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






39. The energy of motion.






40. A swing back and forth at a regular rate.






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






42. A toothed wheel that works with others to alter the relation between the speed of an engine and the speed of the driven parts.






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






44. A machine consisting of two turning objects attached to each other at thier centers. One object to turn






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






46. A combo of several pulleys working together.






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






48. The distance between adjacent threads in a screw.






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






50. A push or pull on an object.
