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. Acts on a certain area.






2. 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.






3. A push or pull on an object.






4. A combo of several pulleys working together.






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






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






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






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






10. Measurement for work






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






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






13. The gear being turned buy the driver gear






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






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






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






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






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






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






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






21. A machine used for raising or moving liquids.






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






23. Work= force x distance






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






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






26. The ability to do work.






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






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






29. A way to measure stuff.






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






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






32. The energy of motion.






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






34. 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.






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






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






37. Stored energy






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






39. 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.






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






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






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






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






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






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






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






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






48. 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.






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






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