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 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.






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






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






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






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






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






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






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






9. Robotic aircraft - used extensively by the military.






10. Aircraft speeds between Mach 5 and 10.






11. Aircraft speeds between Mach 1 and 5.






12. 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.






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






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






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






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






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






18. A glider designed for sustained flight.






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






20. Aircraft speeds under Mach 1.






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






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






23. To set or thrust in motion.






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






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






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






27. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






43. 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.






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






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






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






47. The ratio of inertial forces to viscous forces.






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






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






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