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






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






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






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






6. Circular movement.






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






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






9. The realtioship between the speed of rotation of a smaller gear and a larger gear = number of driven gear teeth / Number of following gear teeth.






10. A combo of several pulleys working together.






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






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






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






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






15. The gear being turned buy the driver gear






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






17. The distance between adjacent threads in a screw.






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






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






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






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






22. A push or pull on an object.






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






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






25. The ability to do work.






26. A way to measure stuff.






27. A machine used for raising or moving liquids.






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






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






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






31. 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.






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






33. The energy of motion.






34. 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.






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






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






37. The ratio of the speed of the driving member of a gear train to that of the driven member.






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






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






40. Stored energy






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






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






43. Movement in a straight line.






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






45. The results of the operation of any system.






46. Work= force x distance






47. 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.






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






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






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