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






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






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






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






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






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






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






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






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






11. Aircraft speeds under Mach 1.






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






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






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






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






16. Aircraft speeds between Mach 1 and 5.






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






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






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






21. 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.






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






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






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






25. Robotic aircraft - used extensively by the military.






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






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






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






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






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






31. Aircraft speeds between Mach 10 and 25.






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






33. To set or thrust in motion.






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






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






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






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






38. A glider designed for sustained flight.






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






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






41. 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.






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






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






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






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






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






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






48. Design machines that fly.






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






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