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. Robotic aircraft - used extensively by the military.






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






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






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






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






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






7. Aircraft speeds under Mach 1.






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






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






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






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






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






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






14. A powered - aerial vehicle that does not carry a human operator - uses aerodynamic forces to provide vehicle lift - can fly autonomously or be piloted remotely - can be expendable or recoverable - and can carry a lethal or nonlethal payload.






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






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






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






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






19. To set or thrust in motion.






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






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






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






23. A glider designed for sustained flight.






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






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






26. 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.






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






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






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






30. 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.






31. Aircraft speeds between Mach 5 and 10.






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






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






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






35. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






49. Design machines that fly.






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