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






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






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






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






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






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






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






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






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






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






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






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






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






15. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






26. 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.






27. A glider designed for sustained flight.






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






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






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






31. To set or thrust in motion.






32. The ratio of inertial forces to viscous forces.






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






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






35. Robotic aircraft - used extensively by the military.






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






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






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






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






41. Aircraft speeds between Mach 5 and 10.






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






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






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






45. Aircraft speeds between Mach 10 and 25.






46. 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.






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






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






49. 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.






50. Design machines that fly.
