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






2. Design machines that fly.






3. The capability of an aircraft to respond to your flight inputs - especially with regard to attitude and flight path.






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






5. Robotic aircraft - used extensively by the military.






6. A reduction in the chord of a wing as measured from the root to the tip of the wing.






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






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






9. A force caused by the gravitational attraction of the Earth.






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






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






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






13. A glider designed for sustained flight.






14. The outline shape of a wing when viewed from above.






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






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






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






18. Aircraft speeds under Mach 1.






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






20. The angle formed by the wing chord line and the relative wind.






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






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






23. A rocket- launched spacecraft able to land like an unpowered aircraft - used for journeys between earth and craft orbiting the earth.






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






25. The written text of a play - film - or broadcast.






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






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






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






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






30. 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.






31. 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.






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






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






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






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






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






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






38. Aircraft speeds between Mach 1 and 5.






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






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






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






42. A structure that creates up and down forces at the tail to keep the fuselage aligned in pitch with the relative wind. The structure itself is horizontal while the forces it creates are vertical.






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






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






45. A large bag filled with hot air or gas to make it rise in the air - with a basket for passengers hanging from it.






46. The space in the fuselage of a small airplane containing seats for the pilot - copilot - and sometimes passengers.






47. To set or thrust in motion.






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






49. 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.






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