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. Force without machine/Force with machine






2. 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






3. Exhaust






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






5. One that pushes on an object






6. A flat - sloping surface -The only simple machine that does not move -The force is applied to the ramp - since this is the direction the load weight is moved -Sloping side is longer than vertical side -Less force is required to accomplish the same am






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






8. What we are not studying






9. Applied at an angle or parallel to a surface






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






11. Static - Dynamic






12. Rotation will not occur - but translation might occur






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






14. 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






15. 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






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






17. 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






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






19. What we are studying






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






21. When the fluid is in motion






22. 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






23. Exhaust of combustion products






24. Force x Distance






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






26. 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

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






28. 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






29. 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 (






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






31. Can be applied at a time on an object






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






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






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

35. 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






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






37. Compression of fuel mix






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






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






40. A combination of components






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






42. 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






43. The branch of science and engineering involving measurement






44. When fluid is at rest






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






46. Intake of fuel and air mix






47. Combustion ignited by spark plug and materials are compressed






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






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






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