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. Aircraft speeds under Mach 1.






2. A glider designed for sustained flight.






3. Aircraft speeds between Mach 10 and 25.






4. The ratio of inertial forces to viscous forces.






5. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






25. Robotic aircraft - used extensively by the military.






26. 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.






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






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






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






30. 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.






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






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






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






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






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






36. To set or thrust in motion.






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






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






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






41. 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.






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






43. Aircraft speeds between Mach 5 and 10.






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






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






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






47. 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.






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






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






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