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






2. Design machines that fly.






3. Aircraft speeds between Mach 10 and 25.






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






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






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






7. Aircraft speeds under Mach 1.






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






9. 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.






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






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






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






13. Aircraft speeds between Mach 5 and 10.






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






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






16. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






24. 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.






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






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






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






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






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






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






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






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






33. A glider designed for sustained flight.






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






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






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






37. 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.






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






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






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






41. To set or thrust in motion.






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






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






44. 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.






45. Aircraft speeds between Mach 1 and 5.






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






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






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






49. 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.






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