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






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






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






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






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






6. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






16. 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.






17. 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.






18. 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.






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






20. To set or thrust in motion.






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






22. 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.






23. Aircraft speeds between Mach 10 and 25.






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






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






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






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






28. The outline shape of a wing when viewed from above.






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






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






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






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






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






34. Design machines that fly.






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






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






37. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






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