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






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






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






4. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






32. Aircraft speeds between Mach 5 and 10.






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






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






35. Aircraft speeds between Mach 10 and 25.






36. The ratio of inertial forces to viscous forces.






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






38. 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.






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






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






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






42. 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.






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






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






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






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






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






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. Design machines that fly.






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