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






2. Movement in a straight line.






3. A back and forth movement.






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






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






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






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






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






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






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






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






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






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






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






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






16. 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.

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






21. The ability to do work.






22. Circular movement.






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






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






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






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






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






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






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






30. 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.






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






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






33. 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.






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






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






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






37. 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.






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






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






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






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






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






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






44. The results of the operation of any system.






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