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. 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.






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






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






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






5. 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.






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






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






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






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






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






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






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






13. A glider designed for sustained flight.






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






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






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






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






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






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






20. Design machines that fly.






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






22. Aircraft speeds between Mach 1 and 5.






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






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






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






26. To set or thrust in motion.






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






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






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






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






31. 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.






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






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






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






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






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






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






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






39. Aircraft speeds between Mach 10 and 25.






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






41. Aircraft speeds under Mach 1.






42. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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