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






3. A glider designed for sustained flight.






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






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






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






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






8. 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.






9. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






20. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






26. 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.






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






28. 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.






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






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






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






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






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






34. Aircraft speeds between Mach 10 and 25.






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






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






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






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






39. Design machines that fly.






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






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






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






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






44. 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.






45. To set or thrust in motion.






46. Robotic aircraft - used extensively by the military.






47. The ratio of inertial forces to viscous forces.






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






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






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