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. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






8. 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.






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






10. 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.






11. Aircraft speeds between Mach 1 and 5.






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






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






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. Robotic aircraft - used extensively by the military.






16. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






33. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






43. Aircraft speeds between Mach 10 and 25.






44. 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.






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






46. To set or thrust in motion.






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






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






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






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