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






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






3. A glider designed for sustained flight.






4. Aircraft speeds between Mach 5 and 10.






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






6. Robotic aircraft - used extensively by the military.






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






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






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






10. 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.






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






12. To set or thrust in motion.






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






14. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






25. Design machines that fly.






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






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






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






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






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






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






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






33. Aircraft speeds under Mach 1.






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






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






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






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






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






39. 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.






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






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






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






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






44. 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.






45. Aircraft speeds between Mach 1 and 5.






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






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






48. 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.






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






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