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 outline shape of a wing when viewed from above.






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






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






4. To set or thrust in motion.






5. 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.






6. 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.






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






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






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






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






11. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






26. 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.






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






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






29. A glider designed for sustained flight.






30. Aircraft speeds between Mach 1 and 5.






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






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






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






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






35. 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.






36. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






45. Aircraft speeds between Mach 10 and 25.






46. Aircraft speeds between Mach 5 and 10.






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






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






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






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