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






2. To set or thrust in motion.






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






4. 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.






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






6. Aircraft speeds between Mach 10 and 25.






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






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






9. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






29. A glider designed for sustained flight.






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






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






33. Robotic aircraft - used extensively by the military.






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






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






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






37. 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.






38. 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.






39. Design machines that fly.






40. 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.






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






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






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






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






45. The ratio of inertial forces to viscous forces.






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






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






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






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






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