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






2. 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.






3. The ratio of inertial forces to viscous forces.






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






5. 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.






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






7. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






15. To set or thrust in motion.






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






17. A glider designed for sustained flight.






18. 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.






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






20. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






47. Design machines that fly.






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






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






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