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






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






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






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






5. 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.






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






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






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






9. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






20. Aircraft speeds under Mach 1.






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






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






23. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






29. Aircraft speeds between Mach 1 and 5.






30. The ratio of inertial forces to viscous forces.






31. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






46. 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.






47. Aircraft speeds between Mach 5 and 10.






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






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






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