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 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.






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. Aircraft speeds between Mach 1 and 5.






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






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. Design machines that fly.






7. Aircraft speeds between Mach 5 and 10.






8. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






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






20. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






35. Aircraft speeds between Mach 10 and 25.






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






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






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






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






40. A glider designed for sustained flight.






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






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






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






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






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






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






47. The ratio of inertial forces to viscous forces.






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






49. Aircraft speeds under Mach 1.






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