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






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






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






4. Aircraft speeds between Mach 1 and 5.






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






6. Aircraft speeds between Mach 10 and 25.






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






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






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






10. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






18. 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.






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






20. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






29. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






45. Design machines that fly.






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






47. The ratio of inertial forces to viscous forces.






48. 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.






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






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