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. If a force causes rotations -Vector- Machines can have more than one torque-Units: foot- pound and newton - meter - i.e. engines - airplanes - propeller






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






3. Can be applied:-By direct contact: push - pull - twist -At a distance: gravity - magnetism Can change: speed - direction - shape - units of force






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

5. ...






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






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






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






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






10. The branch of science and engineering involving measurement






11. A pull on an object






12. A change in velocity over time -Unites: USA- ft/s^2 and SI: m/s^2






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






14. 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






15. Can be applied at a time on an object






16. 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

17. Compression of fuel mix






18. Ignition - power stroke






19. Compression-Tension-Shear






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






21. Body at rest or is in equilibrium (wall)






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






23. 1. Magnitude: size - a numberi.e. 50 mph 2. Direction: angle i.e. N -E -W -S






24. 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






25. Work/force or vertical distance/sloping distance






26. Mass can neither by created nor destroyed - only transformed






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






28. Piston travels up and both plugs are closed






29. Rotation will not occur - but translation might occur






30. ICE generates electricity for electric battery -Electric motor turns wheels






31. Modern Technology- More efficient-Better Cooling-Easier to service- longer life - lither weight- More expensive






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






33. What we are not studying






34. 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






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






36. The magnitude of something in a particular direction






37. Exhaust






38. Combustion of fuel mixture ignited by spark plug






39. When the moving fluid is a gas






40. When the work done by the effort exceeds the work done by the load - the load...






41. Applied at an angle or parallel to a surface






42. Air is drawn in






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






44. Often a free body has _______ acting on it






45. Exhaust of combustion products






46. 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






47. A movement around a central pivot point (rotational movement) -Units: revolutions per second (rps) and revolutions per minute (rpm)






48. 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






49. Mass x acceleration






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