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. 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






2. The standard system of units that uses base 10 and used in the rest of the world. US does not use - but Great Britain does - Base Units: mass - kilograms (kg) - length- meters (m) - and time-Seconds (S) - Force is a derived unit measured in newtons (






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






4. Liquid or gas






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






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






7. Piston travels up and both plugs are closed






8. Rotation will not occur - but translation might occur






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






10. When the sum of all forces and the sum of all moments both equal forces - No movement






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

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






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






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






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






16. Combustion of fuel mixture ignited by spark plug






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






18. When two parallel forces equal in magnitude and opposite direction - i.e. steering wheel - turn a know - turn on and off a faucet






19. Force without machine/Force with machine






20. 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






21. Can be applied at a time on an object






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






23. A pull on an object






24. The amount of atoms and molecules in something - Matter is energy that has become solid -An object gains mass when it gains more energy and vice a versa -Units: SI- kgs and USA: Slugs - lbs






25. Dimensions and units






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






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






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






29. 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






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






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






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






33. 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






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






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






36. Length / Time






37. Result of gravity acting on mass -The greater the mass - the greater the weight -Is a force -Units: lbs - N






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






39. Movement along a line (reciprocal or linear motion) -Units: feet and meters






40. Air is compressed - work is done on the system






41. 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






42. Compression of fuel mix






43. (Force)(Distance)/Seconds






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






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






46. Both engines drive wheels -ICE used for cruising -Electric motor assists with low speed for acceleration and hill climbing






47. A combination of components






48. 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






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






50. Applied at an angle or parallel to a surface
