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






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






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






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






5. Design machines that fly.






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






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






8. 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.






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






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






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






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






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






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






15. A glider designed for sustained flight.






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






17. 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.






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






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






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






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






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






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






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






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






26. 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.






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






28. 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.






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






30. Aircraft speeds between Mach 1 and 5.






31. Robotic aircraft - used extensively by the military.






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






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






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






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






36. Aircraft speeds between Mach 10 and 25.






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






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






39. Aircraft speeds under Mach 1.






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






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






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






43. To set or thrust in motion.






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






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






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






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






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






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






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