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. Aircraft speeds between Mach 5 and 10.






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






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






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






5. Robotic aircraft - used extensively by the military.






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






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






8. Aircraft speeds between Mach 10 and 25.






9. 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.






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






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






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






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






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






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






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






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






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






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






20. A straight line through the center of gravity of the aircraft and at 90






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






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






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






24. To set or thrust in motion.






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






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






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






28. Aircraft speeds under Mach 1.






29. 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.






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






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






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






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






34. A glider designed for sustained flight.






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






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






37. Aircraft speeds between Mach 1 and 5.






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






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






40. 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.






41. 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.






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






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






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






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






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






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






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






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






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