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 rotating wheel- like device with teeth around the rim.






2. Work= force x distance






3. Movement in a straight line.






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






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






6. Acts on a certain area.






7. A twisting force.






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






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






10. A machine used for raising or moving liquids.






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






12. Measurement for work






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






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






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






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






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






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






19. Stored energy






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






21. The results of the operation of any system.






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






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






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






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






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






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






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






29. 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.






30. A combo of several pulleys working together.






31. The energy of motion.






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






33. The ability to do work.






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






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






36. A push or pull on an object.






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






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






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






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






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






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






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






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






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






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






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






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






49. Circular movement.






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