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. The force acting perpendicular to a certain surface area.






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






3. A machine used for raising or moving liquids.






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






5. Acts on a certain area.






6. The distance between adjacent threads in a screw.






7. A combo of several pulleys working together.






8. Measurement for work






9. The ability to do work.






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






11. 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.






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






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






14. The gear being turned buy the driver gear






15. Circular movement.






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






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






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






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






20. The energy of motion.






21. Work= force x distance






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






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






24. 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.






25. 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.






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






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






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






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






30. A back and forth movement.






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






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






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






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






36. A push or pull on an object.






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






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






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






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






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






42. 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.


43. 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.






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






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






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






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






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






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






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