Mechanical Engineering

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. Pistons connected to crankshaft -1 stroke up - 1 stroke down of the piston -1 rotation of the piston -Problems: high emissions - noisy - inefficient - high vibrations - unburnt fuel - burnt oil -Benefits: small and light -Being phased out in USA - i.






2. An application of Pascal's Principle (trading distance and force while doing the same amount of work) -Gives a mechanical advantage -The muscles of machines - used to produce very large forces - use a fluid under pressure (gas is low pressure and liq






3. An indication of kinetic energy of mass at the molecular level






4. Same pressure - work - volume - Different forces and distances






5. More compact (size of beer keg) - No valves -Benefits: fewer parts - lower engine weight Problems: seal - lower inertia forces -1 rotar=3 to 4 pistons






6. Length x Width x Height






7. A pull on an object






8. What we are not studying






9. Piston travels up and both plugs are closed






10. When the moving fluid is a gas






11. Compression-Tension-Shear






12. Every object continues in motion in a straight line unless acted upon by some force -Every object at rest continues at rest unless acted upon by a force -So forces cause a change in an object's state of motion

13. The perpendicular distance from the pivot point to the point of application of the force (d) - M=Fd -Clockwise=Negative moment -Counterclockwise=Positive moment






14. In a right triangle - the sum of the squares of the sides equals the square of the hypotenous






15. When the fluid is in motion






16. Incompressible (volume doesnt change) Transmit force evenly - Lubricates - Trap contaminants - Some based on vegetable oils - Biodegradable - Aircraft fluids noncombustible (thins as temperature rises)






17. Causes acceleration -Units: USA: 32.2 ft/s^2 SI: 9.8 m/sec^2






18. Often a free body has _______ acting on it






19. Rotation may occur






20. Used to measure or quantify -US Common: Absolute and Gravitational -SI: absolute






21. Compression of fuel mix






22. A quantity that has both magnitude and direction when placed within a coordinate system -Forces and Velocity i.e. driving 50 miles to the northeast






23. Ignition - power stroke






24. Combine two or more power sources - locomotives - buses (diesel- electric) -Submarines (Nuclear- electric) -Components:gas engine - fuel tank - electric motor - generator - batteries - transmission -2 motors: Internal Combustion Engine and Electric E






25. A^2+b^2=c^2






26. Describes how applied forces bring a body into rest or equilibrium






27. Combustion of fuel mixture ignited by spark plug






28. Result of a force moving an object against a resistance through some distance in a desired direction -Work transfers energy -Work is a measure of what is done and not the effort applied - Done by lifting - pushing - rotating - or sliding -W=Fd -F=Amo






29. Piston travels up and exhaust valve opens. Combustion by product exhaustion






30. Length / Time






31. (Force)(Distance)/Seconds






32. Derived from - or composed of - base dimensions i.e. Area (length x width) - Weight (mass x acceleration) - velocity (length/time)






33. Energy may enter or leave. Mass can enter or leave the system i.e. open water bottle - molecule - hydraulic cylinder - human






34. Energy may enter or leave. No mass enters or leaves the system i.e. Closed water bottle - car engine - human






35. Body in motion (car)






36. For every action there is an equal and opposite reaction -Force -F=mg -Earth exerts a force on all of us

37. Liquid or gas






38. The branch of science and engineering involving measurement






39. External Combustion engine -Only used in factories and plants (not used in cars)






40. Exhaust of combustion products






41. Air is drawn in






42. Force/Area






43. In a hydraulic with an incompressible fluid - the total pressure at any point in the system is the same - liquid

44. When a simple machine increases a force it is at the expense of a ____ in the distance the load is moved






45. Friction changes KE to heat energy- Heat is transferred to air- Front brakes work harder than rear- Some brakes use asbestos- Newer cars have dual braking systems - Don't drive through water or your brakes won't work well (ride breaks to dry them out






46. When the work done by the effort just equals the work done by the load - ______ of the machine will occur






47. Fuel is injected and combusts due to temperature of compressed air






48. Mechanics is an application of math that describes how forces affect a body






49. Four Stroke Engine -Used in hotter areas because more efficient -Higher compression ratio than gasoline






50. Two stroke- Four Stroke- Diesel-Rotary -Hybrid
