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. Aircraft speeds under Mach 1.






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






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






4. Control surfaces attached to the trailing edge of the wing extending outward from the fuselage to the midpoint of each wing. Flaps can increase the lifting efficiency of the wing and decrease stall speed.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






19. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






34. Aircraft speeds between Mach 1 and 5.






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






36. Design machines that fly.






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






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






39. 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.






40. To set or thrust in motion.






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






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






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






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






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






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






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






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






49. The ratio of inertial forces to viscous forces.






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