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






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






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






4. 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.






5. 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.






6. A combo of several pulleys working together.






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






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






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






10. A push or pull on an object.






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






12. The energy of motion.






13. A back and forth movement.






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






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






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






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






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






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






20. A machine used for raising or moving liquids.






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






22. Circular movement.






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






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






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






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






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






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






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






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






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






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






33. The ability to do work.






34. The results of the operation of any system.






35. 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.






36. 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.






37. A way to measure stuff.






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






39. The gear being turned buy the driver gear






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






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






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






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






44. 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.






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






46. Work= force x distance






47. Acts on a certain area.






48. Stored energy






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






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