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






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






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






4. 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.






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






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






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






8. 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.






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






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






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






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






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






14. To set or thrust in motion.






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






16. A glider designed for sustained flight.






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






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






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






20. Aircraft speeds between Mach 10 and 25.






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






22. Design machines that fly.






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






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






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






26. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






46. Robotic aircraft - used extensively by the military.






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






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






49. The ratio of inertial forces to viscous forces.






50. Aircraft speeds under Mach 1.
