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






2. 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.






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






4. A glider designed for sustained flight.






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






6. Design machines that fly.






7. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






18. 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.






19. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






34. Aircraft speeds between Mach 5 and 10.






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






36. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






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






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






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






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