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






2. To set or thrust in motion.






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






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






5. 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.






6. 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.






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






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






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






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






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






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






13. Robotic aircraft - used extensively by the military.






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






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






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






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






18. A glider designed for sustained flight.






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






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






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






23. 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.






24. Aircraft speeds under Mach 1.






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






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






27. 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.






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






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






30. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






47. Aircraft speeds between Mach 10 and 25.






48. The ratio of inertial forces to viscous forces.






49. Aircraft speeds between Mach 1 and 5.






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