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






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






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






4. 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.






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






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






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






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






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






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






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






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






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






14. 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.






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






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






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






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






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. A glider designed for sustained flight.






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






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






23. The ratio of inertial forces to viscous forces.






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






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






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






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






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






29. To set or thrust in motion.






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






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






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






34. Design machines that fly.






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






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






38. 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.






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






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






41. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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