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 glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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






13. 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.






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






15. To set or thrust in motion.






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






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






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






19. Design machines that fly.






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






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






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






23. Aircraft speeds between Mach 1 and 5.






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






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






26. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






35. 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.






36. 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.






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






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






39. Aircraft speeds under Mach 1.






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






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






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






43. 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.






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






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






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






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






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






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






50. 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.
