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






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






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






4. Design machines that fly.






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






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






7. 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.






8. Aircraft speeds between Mach 10 and 25.






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






10. Aircraft speeds under Mach 1.






11. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






21. 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.






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






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






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






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






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






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






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






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






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






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






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






33. To set or thrust in motion.






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






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






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






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






38. A glider designed for sustained flight.






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






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






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






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






43. Aircraft speeds between Mach 1 and 5.






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






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






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






47. Robotic aircraft - used extensively by the military.






48. 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.






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






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