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






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






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






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






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






6. Aircraft speeds under Mach 1.






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






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






9. The ratio of inertial forces to viscous forces.






10. A glider designed for sustained flight.






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






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






13. 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.






14. Design machines that fly.






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






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






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






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






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






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






21. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






32. 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.






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






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






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






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






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






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






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






40. 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.






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






42. 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.






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






44. Robotic aircraft - used extensively by the military.






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






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






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






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






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






50. Aircraft speeds between Mach 1 and 5.
