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






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






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






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






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






6. Aircraft speeds between Mach 10 and 25.






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






8. To set or thrust in motion.






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






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






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






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






13. The ratio of inertial forces to viscous forces.






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






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






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






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






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






19. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






28. 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.






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






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






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






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






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






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






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






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






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






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






39. 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.






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






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






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






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






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






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






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






47. Aircraft speeds under Mach 1.






48. A glider designed for sustained flight.






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






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