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






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






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






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






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






6. Aircraft speeds between Mach 1 and 5.






7. Design machines that fly.






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






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






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






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






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






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






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






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






16. Aircraft speeds under Mach 1.






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






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






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






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






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






22. To set or thrust in motion.






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






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






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






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






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






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






29. An advertising film which promotes a product in an informative and supposedly objective style.






30. 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.






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






32. A glider designed for sustained flight.






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






34. Aircraft speeds between Mach 5 and 10.






35. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






42. A large bag filled with hot air or gas to make it rise in the air - with a basket for passengers hanging from it.






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






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






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






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






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






48. 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.






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






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