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






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






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






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






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






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






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






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






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






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






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






12. To set or thrust in motion.






13. A glider designed for sustained flight.






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






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






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






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






18. 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.






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






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






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






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






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






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






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






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






28. 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.






29. 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.






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






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






32. Design machines that fly.






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






34. Robotic aircraft - used extensively by the military.






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






36. The ratio of inertial forces to viscous forces.






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






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






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






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






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






42. Aircraft speeds between Mach 1 and 5.






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






44. Aircraft speeds under Mach 1.






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






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






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






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






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






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