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 - 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.






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






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






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






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






6. 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.






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






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






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






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






11. A glider designed for sustained flight.






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






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






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






15. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






26. Aircraft speeds under Mach 1.






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






28. 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.






29. 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.






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






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






32. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






41. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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