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






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






3. Robotic aircraft - used extensively by the military.






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






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






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






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






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






9. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






17. To set or thrust in motion.






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






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






20. Aircraft speeds under Mach 1.






21. A glider designed for sustained flight.






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






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






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






25. 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.






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






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






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






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






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






31. 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.






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






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






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






35. The movement about the vertical axis produced by the rudder and controlled by pedals.






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






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






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






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






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






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






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






44. The ratio of inertial forces to viscous forces.






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






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






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






48. Aircraft speeds between Mach 10 and 25.






49. Aircraft speeds between Mach 5 and 10.






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