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 rate at which temperature decreases with an increase in altitude.






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






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






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






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






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






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






10. The ratio of inertial forces to viscous forces.






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






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






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






14. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






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






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






27. Aircraft speeds between Mach 10 and 25.






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






29. 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.






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






31. Aircraft speeds between Mach 1 and 5.






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






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






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






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






36. Aircraft speeds between Mach 5 and 10.






37. 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.






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






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






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






41. Robotic aircraft - used extensively by the military.






42. Design machines that fly.






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






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






45. 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.






46. A glider designed for sustained flight.






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






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






49. Aircraft speeds under Mach 1.






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