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 ability to do work.






2. A machine used for raising or moving liquids.






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






4. The gear being turned buy the driver gear






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






6. A way to measure stuff.






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






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






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






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






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






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






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






14. Movement in a straight line.






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






16. A pivot pin near the outside edge of a wheel or disk that changes reciprocating motion into rotary motion.






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






18. Circular movement.






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






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






22. A combo of several pulleys working together.






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






24. Work= force x distance






25. The results of the operation of any system.






26. Stored energy






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






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






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






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






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






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






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






34. The distance between adjacent threads in a screw.






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






36. The energy of motion.






37. A common workplace disorder causing numbness and pain in the thumb and first three finger.






38. Measurement for work






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






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






41. A push or pull on an object.






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






44. 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.






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






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






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






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






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






50. 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.
