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.

10. Movement in a straight line.






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






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






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






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






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






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






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






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






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






20. 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.






21. Measurement for work






22. 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.

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






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






30. 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.






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






32. The ability to do work.






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






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






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






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






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






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






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






41. The results of the operation of any system.






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






43. The gear being turned buy the driver gear






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






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






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






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






48. A back and forth movement.






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