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 rate at which temperature decreases with an increase in altitude.






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






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






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






5. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






14. 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.






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






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






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






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






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






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






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






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






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






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






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






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






27. The ratio of inertial forces to viscous forces.






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






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






30. To set or thrust in motion.






31. Aircraft speeds under Mach 1.






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






33. Aircraft speeds between Mach 5 and 10.






34. Aircraft speeds between Mach 1 and 5.






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






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






37. Robotic aircraft - used extensively by the military.






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






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






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






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






42. 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.






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






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






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






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






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






48. 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.






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






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