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 combo of several pulleys working together.






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






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






4. 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.

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






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






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






18. 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.

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






27. A push or pull on an object.






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






29. Acts on a certain area.






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






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






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






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






34. Movement in a straight line.






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






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






37. The distance between adjacent threads in a screw.






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






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






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






41. Work= force x distance






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






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






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






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






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






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






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






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






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