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 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.






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






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






4. A glider designed for sustained flight.






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






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






7. Aircraft speeds under Mach 1.






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






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






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






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






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






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






14. To set or thrust in motion.






15. 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.






16. Robotic aircraft - used extensively by the military.






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






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






19. The ratio of inertial forces to viscous forces.






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






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






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






23. 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.






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






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






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






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






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






29. 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.






30. Design machines that fly.






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






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






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






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






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






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






37. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






47. 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.






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






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






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