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






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






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






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






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






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






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






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






9. 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.






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






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






12. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






18. 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.






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






20. Design machines that fly.






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






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






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






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






25. Aircraft speeds between Mach 10 and 25.






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






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






28. The ratio of inertial forces to viscous forces.






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






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






31. 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.






32. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






50. Aircraft speeds between Mach 1 and 5.
