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 wheel with a grooved rim to guide a rope or chain that runs along the groove; used to transmit or change direction of force.






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






3. A machine used for raising or moving liquids.






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






5. Movement in a straight line.






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






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






8. The gear being turned buy the driver gear






9. Acts on a certain area.






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






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






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






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






14. A push or pull on an object.






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






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






17. The ability to do work.






18. The results of the operation of any system.






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






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






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






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






23. Measurement for work






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






25. A twisting force.






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






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






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






29. The distance between adjacent threads in a screw.






30. 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.






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






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






33. A combo of several pulleys working together.






34. 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.






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






36. 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.






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






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






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






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 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.

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






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






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






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






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






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






48. A back and forth movement.






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






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