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






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






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






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






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






7. Aircraft speeds under Mach 1.






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






9. Aircraft speeds between Mach 10 and 25.






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






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






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






13. Aircraft speeds between Mach 1 and 5.






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






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






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






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






18. 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.






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






20. Robotic aircraft - used extensively by the military.






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






22. A glider designed for sustained flight.






23. The ratio of inertial forces to viscous forces.






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






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






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






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






28. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






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






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






41. 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.






42. 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.






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






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






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






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






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






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






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






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