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. Design machines that fly.






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






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






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






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






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






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






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






9. The rate at which temperature decreases with an increase in altitude.






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






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






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






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






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






15. 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.






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






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






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






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






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






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






22. A glider designed for sustained flight.






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






24. The ratio of inertial forces to viscous forces.






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






26. 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.






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






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






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






30. To set or thrust in motion.






31. 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.






32. 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.






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






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






35. Robotic aircraft - used extensively by the military.






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






37. 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.






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






39. Aircraft speeds between Mach 5 and 10.






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






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






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






43. Aircraft speeds under Mach 1.






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






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






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






47. Aircraft speeds between Mach 10 and 25.






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






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






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