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 force caused by the gravitational attraction of the Earth.






2. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






8. Aircraft speeds under Mach 1.






9. Robotic aircraft - used extensively by the military.






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






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






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






13. 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.






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






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






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






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






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






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






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






21. The ratio of inertial forces to viscous forces.






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






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






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






25. A glider designed for sustained flight.






26. 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.






27. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






36. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






47. To set or thrust in motion.






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






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






50. 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.
