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 relationship between the length and width of a wing.






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






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






4. 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.






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






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






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






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






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






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






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






12. Design machines that fly.






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






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






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






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






17. 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.






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






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






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






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






22. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






29. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






40. The ratio of inertial forces to viscous forces.






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






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






43. To set or thrust in motion.






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






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






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






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






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






49. Aircraft speeds between Mach 1 and 5.






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