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






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






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






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






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






7. 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.






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






9. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






30. To set or thrust in motion.






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






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






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






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






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






36. Design machines that fly.






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






38. 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.






39. 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.






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






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






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






43. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






49. The ratio of inertial forces to viscous forces.






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