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. To set or thrust in motion.






2. The study of forces and the resulting motion of objects through the air.






3. A short - memorable phrase used in advertising or associated with a political party or group.






4. Generates the lifting force that helps the airplane fly when air flows around it.






5. The flat surfaces located behind the center of gravity tend to weathervane with the wind.






6. A built in twist in the wing so that the trailing edge at the wingtip is raised (Wash out) or lowered (Wash in). This significantly affects the slow flight and stall characteristics of the wing.






7. Acts in the opposite direction of flight - opposes the forward- acting force of thrust - and limits the forward speed of the aircraft.






8. A vehicle - missile - or aircraft which obtains thrust by the reaction to the ejection of fast moving exhaust from within a rocket engine.






9. Any surface - such as a wing - which provides aerodynamic force when it interacts with a moving stream of air.






10. An aircraft with floats or skis instead of wheels - designed to land on and take off from water.






11. A straight line through the center of gravity of the aircraft and at 90






12. Branch of technology and industry concerned with aviation and space flight.






13. Aircraft speeds under Mach 1.






14. Motion around the lateral axis caused by deflection in the elevator controlled by moving the yoke forward and aft.






15. A type of aircraft deriving both lift and propulsion from one or two sets of horizontally revolving rotors.






16. Control surfaces attached to the trailing edge of the wing extending outward from the fuselage to the midpoint of each wing. Flaps can increase the lifting efficiency of the wing and decrease stall speed.






17. A powered heavier- than - air aircraft with fixed wings from which the aircraft derives most of its lift.






18. Consists of both the engine and propeller in a small airplane.






19. Hinged main surface part that help control banking for a turn






20. A rear vertical stabilizer that controls side- to- side or yawing motion of the aircraft nose.






21. The horizontal line that passes through the center of gravity of the aircraft - perpendicular to its flight path.






22. The movement about the vertical axis produced by the rudder and controlled by pedals.






23. The art and science of designing - building - and operating manned or unmanned space objects






24. The relationship between the length and width of a wing.






25. The last point on an airfoil that interacts with the airflow around the wing.






26. The force that created by the effect of airflow as it passes over and under the wing.






27. Rolling motion about the longitudinal axis caused by ailerons deflecting in opposite directions and controlled by twisting the yoke.






28. An aircraft that is designed to fly without an engine.






29. A power- driven aircraft kept buoyant by a body of gas (usually helium) which is lighter than air.






30. Houses the cabin - the cockpit and is a common attachment point for the other major components.






31. An advertising film which promotes a product in an informative and supposedly objective style.






32. A glider designed for sustained flight.






33. Robotic aircraft - used extensively by the military.






34. The part of the airfoil that meets the airflow first.






35. Mach. A decimal number representing the true airspeed relationship to the local speed of sound.






36. The distance from wing tip to wing tip of a wing planform.






37. A straight line parallel to the length of the fuselage but that runs through the aircraft's center of gravity.






38. Aircraft speeds between Mach 5 and 10.






39. A thin layer of air next to the surface of an airfoil which shows a reduction in speed due to the air's viscosity.






40. Caused by the separation of airflow from the wing's upper surface resulting in a rapid decrease in lift.






41. Aircraft speeds between Mach 10 and 25.






42. A rear horizontal stabilizer that controls up and down or pitching motion of the aircraft nose.






43. The tail assembly of an aircraft - including the horizontal and vertical stabilizers - elevators and rudder.






44. The study or practice of travel through the air.






45. Forward- acting force which opposes drag and propels the aircraft through the air.






46. A short - easily- remembered slogan - verse - or tune.






47. Aircraft stability is the characteristic of an airplane in flight that causes it to return to a condition of equilibrium - or steady flight - after it is disturbed.






48. The rate at which temperature decreases with an increase in altitude.






49. Aircraft speeds between Mach 1 and 5.






50. The common reference point for the three axes of the aircraft.
