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. The designing of machines that contribute to society and our quality of life - Mechanical engineers apply the principles of mathematics - chemistry - and physics to solve real- world problems






2. 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






3. What we are not studying






4. When fluid is at rest






5. Compression of fuel mix






6. The force simple machines use to do work on a single load or against a single force






7. A flat - two dimensional property -Units of length multiplied by length describe area -A=length x width






8. A fluid power system uses hydraulics and a fluid under pressure to create a greater force than is applied






9. Can be applied at a time on an object






10. Intake of fuel and air mixture - compression of mixture by piston






11. Allows comparison between different measuring systems and units - Necessary to market internationally






12. A small piece that makes up a larger whole. Each component is there for a specific job - but the sum of components






13. Often a free body has _______ acting on it






14. The branch of science and engineering involving measurement






15. Combustion of fuel mixture ignited by spark plug






16. The magnitude of something in a particular direction






17. (Force)(Distance)/Seconds






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

19. Old technology- harder to service-Still used on big trucks and trailers because they are too expensive to convert






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






21. Length / Time






22. Length x Width






23. A pull on an object






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






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






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






27. ...






28. Tells us how fast work is done - varies with time (more power is needed to do work in less time - and less power is needed to do work in more time) =Fd/s -Units: USA: ft- lb/s SI: watts (J/S)






29. Can be reduced by decreasing the weight or force or increasing the area i.e. airbag






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






31. Compression-Tension-Shear






32. If the force needed to operate the machine (input force) is less than the force being opposed or the load being moved (output force) -The ratio of the output force divided by the input force -If the number is greater than one - there is a mechanical






33. Rotation may occur






34. A device that uses energy to do work to accomplish some desired activity - They do not produce energy - but they do transmit and transform energy - Machines can transmit a force - control its motion - and change its direction - a system of components






35. Varies by location (on earth) - distance (from earth) - and mass (of planet)






36. 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






37. Brake pedal and linkage - Master Cylinder - Wheel cylinders (4) - Hydraulic lines - Hydraulic fluid - Mechanical advantage is provided by the foot pedal to the booster (level) - A greater force is applied on the wheel cylinders than on the brake peda






38. Body in motion (car)






39. Three- dimensional property measured in units of length times length times length =length x width x height






40. Piston travels down and intake valve is opened. Intake of fuel and air into chamber






41. Length x Width x Height






42. A system adopted from an old British system of units in the 13th century -Engineering system -Units: length- foot (ft) - time- second (s) - force-(lbs) - Mass is a derived unit called a slug -Political/Economic choice -Awkward






43. Piston travels up and both plugs are closed






44. What we are studying






45. Are independent of other dimensions - They are limited in number - length - mass - time - temperature - force






46. Used in cars -2 rotations of crankshaft -4 strokes (down - up - down - up) of piston - i.e. cars - trucks - planes - buses - motorcycles - submarine -1% of gas actually moves people






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






48. 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

49. Force/Area






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