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






2. Robotic aircraft - used extensively by the military.






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






4. The mounting of wings so that the wingtips and higher than the wingroot.






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






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






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






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






9. Aircraft speeds under Mach 1.






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






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






12. 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.






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






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






15. Aircraft speeds between Mach 1 and 5.






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






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






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






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






20. To set or thrust in motion.






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






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






23. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






30. Aircraft speeds between Mach 10 and 25.






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






32. Design machines that fly.






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






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






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






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






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






38. 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.






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






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






41. A glider designed for sustained flight.






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






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






44. 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.






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






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






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






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






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






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