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






3. Robotic aircraft - used extensively by the military.






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






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






6. Characteristic of the aircraft that permits you to maneuver it easily and allows it to withstand the stress resulting from the maneuver.






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






8. Aircraft speeds between Mach 1 and 5.






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






10. Design machines that fly.






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






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






13. Forces and moments on the body caused by a disturbance tend initially to return the body toward its equilibrium position.






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






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






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






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






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






19. 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.






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






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






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






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






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






25. Aircraft speeds between Mach 10 and 25.






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






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






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






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






30. A sequence of drawings representing the shots planned for a film or television production.






31. 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.






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






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






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






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






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






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






38. A glider designed for sustained flight.






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






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






41. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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