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






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






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






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






5. A glider designed for sustained flight.






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






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






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






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






10. To set or thrust in motion.






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






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






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






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






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






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






17. 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.






18. 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.






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






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






21. Design machines that fly.






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






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






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






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






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






27. 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.






28. 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.






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






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






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






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






33. Aircraft speeds between Mach 5 and 10.






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






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






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






37. 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.






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






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






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






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






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






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






44. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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