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. Design machines that fly.






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






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






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






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






7. Aircraft speeds between Mach 10 and 25.






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






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






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






11. 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.






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






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






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






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






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






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






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






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






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






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






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






23. Aircraft speeds under Mach 1.






24. To set or thrust in motion.






25. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






32. 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.






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






34. 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.






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






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






37. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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






49. 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.






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