Mechanical Systems 2

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






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






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






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






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






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






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

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






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






11. Acts on a certain area.






12. A machine used for raising or moving liquids.






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






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






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






16. 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.

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






25. A back and forth movement.






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






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






28. Circular movement.






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






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






31. A push or pull on an object.






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






33. The gear being turned buy the driver gear






34. A twisting force.






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






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 system having a boundary that separates it from it surroundings.






38. 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.






39. 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.






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






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






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






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






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






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






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






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






48. A way to measure stuff.






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






50. Measurement for work
