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






3. 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.






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






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






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






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






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






9. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






19. 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.






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






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






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






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






24. Robotic aircraft - used extensively by the military.






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






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






27. Aircraft speeds between Mach 5 and 10.






28. Design machines that fly.






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






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






33. The ratio of inertial forces to viscous forces.






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






35. Aircraft speeds between Mach 10 and 25.






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






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






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






41. 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.






42. To set or thrust in motion.






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






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






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






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






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






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






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






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