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 load is between the fulcrum and the effort.






2. Work= force x distance






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






4. The results of the operation of any system.






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






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






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






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






9. 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.






10. The distance between adjacent threads in a screw.






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






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






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






14. A combo of several pulleys working together.






15. A back and forth movement.






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






17. Movement in a straight line.






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






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






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






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






22. 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.






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






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






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






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






27. The ability to do work.






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






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






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






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






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






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






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






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






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






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






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






39. Circular movement.






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






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 twisting force.






43. The energy of motion.






44. Acts on a certain area.






45. 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.






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






47. A machine used for raising or moving liquids.






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






49. A push or pull on an object.






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