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






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






3. Aircraft speeds between Mach 5 and 10.






4. Aircraft speeds between Mach 1 and 5.






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






6. 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.






7. 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.






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






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






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






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






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






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






14. 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.






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






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






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






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






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






20. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






35. Aircraft speeds under Mach 1.






36. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






47. The ratio of inertial forces to viscous forces.






48. To set or thrust in motion.






49. A glider designed for sustained flight.






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