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 application of force that moves an object a certain distance.






2. 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.






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






4. The distance between adjacent threads in a screw.






5. 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.

8. 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.






9. Movement in a straight line.






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






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






12. The ability to do work.






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






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






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






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






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






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






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






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






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






22. A twisting force.






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






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






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






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






27. Acts on a certain area.






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






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






30. A combo of several pulleys working together.






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






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






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






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






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






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






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






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






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






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






41. Stored energy






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






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






44. The energy of motion.






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






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






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






48. Work= force x distance






49. The results of the operation of any system.






50. 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.
