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






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






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






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






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






6. Measurement for work






7. The distance between adjacent threads in a screw.






8. A machine consisting of a bar that is free to rotate around a fixed point - changing the amount of force that must be exerted to move an object.






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






10. The gear being turned buy the driver gear






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






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






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






14. A machine consisting of a small cylinder - a crank or handle - on a cable. Winch can be used to lift or pull things






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






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






17. Stored energy






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






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






20. The results of the operation of any system.






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






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






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






24. A back and forth movement.






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






26. Work= force x distance






27. A push or pull on an object.






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






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






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






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






32. Circular movement.






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






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






35. Movement in a straight line.






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






37. A combo of several pulleys working together.






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






39. The ability to do work.






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






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






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






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






44. One of a pair of gears used to connect two shafts whose axes intersect.






45. A machine used for raising or moving liquids.






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






47. The energy of motion.






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






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






50. 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.
