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






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






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






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






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






6. The ability to do work.






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






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






9. 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.






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






11. The that has a handle because of a motoe or person turning it.






12. A way to measure stuff.






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






14. Work= force x distance






15. 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.

16. Circular movement.






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






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






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






20. Acts on a certain area.






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






22. The gear being turned buy the driver gear






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






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






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






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






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






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






29. 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.






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






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






32. A push or pull on an object.






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






34. A twisting force.






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






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






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






38. Movement in a straight line.






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. A machine used for raising or moving liquids.






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






42. Measurement for work






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






44. The distance between adjacent threads in a screw.






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






46. A combo of several pulleys working together.






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






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






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






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