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. Do the work easier






2. Used to control the flow of a fluid. It is a moveable part that controls the flow by opening or closing






3. Distance between the fulcrum and the load






4. F x d






5. Are used to overcome the frictional force of the machine






6. Science of designing machines to suit people






7. Energy is transferred from one place to another - and no energy is changed or converted.






8. Mass of the object lifted by the lever






9. A rigid bar or plank that can rotate around a fixed point






10. Force of the small piston/area of the small piston = Force of the large piston/Area of the large piston






11. The comparison of the force produced by a machine to the force applied to the machine. (the size of the load vs the size of the force needed to move the load)






12. Do not seal the gas (usually air)






13. A very complex combination of pulleys - including fixed and movable is called






14. A large gear driving a smaller gear decreases torque and increases speed in the driven gear






15. A pair of wheels that have teeth that interlink. When they rotate together - one gear wheel transfers turning motion and force to the other.






16. Load Force (FL)/Effort Force (FE)






17. Energy of motion






18. Unit of measurement for pressure






19. Use the force of a liquid in a confined space - apply two essential characteristic of fluids - their incompressibility and their ability to transmit pressure






20. Transferred to kinetic energy in machines in a dam to generate electrical energy






21. Is the work needed to use - or operate the machine






22. Several simple machines all working together in a system






23. The production of large quantities of a standardized article (often using assembly line techniques)






24. Act like levers






25. The ratio of the output to the input of any system - a comparison of the useful work provided by a machine or a system with - the work supplied to the machine or system






26. Hydraulic system in your body






27. Used to apply force to the fluid - which creates pressure in the fluid






28. (driven gear) smaller gear






29. Pressure applied to an enclosed fluid is transmitted undiminished in all directions throughout the fluid and perpendicular to the walls of the container.

30. The combustion occurs inside the engine. The pistons goes through 4 steps: Intake stroke (taking in the fuel) - compression stroke (compressing the fuel- air mixture) - power stroke (the fuel- air mixture is ignited) - exhaust stroke (waste products






31. A small gear driving a larger gear increases torque and reduces speed in the driven gear






32. Bigger gear






33. Required a large shift in population from rural areas to the cities.






34. Consists of a wire - rope - or cable moving on a grooved wheel. One or more combinations of wheels and ropes can be fixed in place or moveable - help you lift larger loads.






35. The rate of motion that an object changes position






36. A group of parts that work together to perform a function






37. Force exerted on the lever to make it move






38. A fixed point






39. Work done by machine / work done to make the machine operate x100






40. F/A






41. Heated water to make steam and then used to move a piston in a circular motion






42. The fluid transfers the pressure from the input piston to the ____________






43. Is the work done by the machine






44. Work unit






45. Do the work faster






46. To increase the force on the output piston - the input piston must move through a greater distance






47. A combination of two wheels of different diameters that turn together - a lever that rotates in a circle around a center point or fulcrum.






48. Reason that machines are never 100% efficient






49. Consists of a small cylinder that has a crank or handle. The axle of the winch acts like the fulcrum - the handle is the effort arm






50. The relationship between the speed of rotations of a smaller gear and a larger gear - can be calculated by dividing the number of driver gear teeth by the number of follower gear teeth.
