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






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






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






4. Aircraft speeds between Mach 5 and 10.






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






6. The ratio of inertial forces to viscous forces.






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






8. Robotic aircraft - used extensively by the military.






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






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






11. 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.






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






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






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






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






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






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






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






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






20. Aircraft speeds between Mach 1 and 5.






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






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






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






24. Design machines that fly.






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






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






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






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






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






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






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






32. 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.






33. 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.






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






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






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






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






38. 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.






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






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






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






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






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






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






45. To set or thrust in motion.






46. Aircraft speeds under Mach 1.






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






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






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






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