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






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






3. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






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






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






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






17. 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.






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






19. The ratio of inertial forces to viscous forces.






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






21. To set or thrust in motion.






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






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






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






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






26. 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.






27. 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.






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






29. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






39. Design machines that fly.






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






41. 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.






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






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






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






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






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






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






48. Robotic aircraft - used extensively by the military.






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






50. Aircraft speeds under Mach 1.
