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






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






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






4. A glider designed for sustained flight.






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






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






7. Aircraft speeds under Mach 1.






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






9. 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.






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






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






12. Aircraft speeds between Mach 5 and 10.






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






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






15. 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.






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






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






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






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






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






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






22. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






31. Design machines that fly.






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






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






34. To set or thrust in motion.






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






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






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






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






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






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






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






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






43. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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