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






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






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






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






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






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






7. The gear being turned buy the driver gear






8. 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.

10. The ability to do work.






11. Work= force x distance






12. The results of the operation of any system.






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






14. 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.






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






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






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






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

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






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






22. A way to measure stuff.






23. 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.






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






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






26. The distance between adjacent threads in a screw.






27. Movement in a straight line.






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






29. The energy of motion.






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






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






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






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






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






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






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. A push or pull on an object.






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






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






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






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






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






43. A back and forth movement.






44. Measurement for work






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






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






47. A machine used for raising or moving liquids.






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






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






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