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






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






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






4. Design machines that fly.






5. A glider designed for sustained flight.






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






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






8. 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.






9. 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.






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






11. 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.






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






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






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






15. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






26. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






37. To set or thrust in motion.






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






39. 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.






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






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






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






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






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






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






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






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






48. The ratio of inertial forces to viscous forces.






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






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