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






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






3. 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.






4. The ratio of inertial forces to viscous forces.






5. 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.






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






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






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






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






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






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






12. 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.






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






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






15. A glider designed for sustained flight.






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






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






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






19. Robotic aircraft - used extensively by the military.






20. Aircraft speeds between Mach 1 and 5.






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






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






23. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






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






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






36. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






47. Aircraft speeds under Mach 1.






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






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






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