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






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






3. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






9. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






17. To set or thrust in motion.






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






19. The ratio of inertial forces to viscous forces.






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






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






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






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






24. Aircraft speeds between Mach 10 and 25.






25. 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.






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






27. 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.






28. Design machines that fly.






29. A glider designed for sustained flight.






30. 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.






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. Robotic aircraft - used extensively by the military.






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






34. Out of its own accord - an aircraft eventually returns to and remains at its equilibrium position over a period of time.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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