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. To set or thrust in motion.






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






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






4. Robotic aircraft - used extensively by the military.






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






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






7. 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.






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






9. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






15. Design machines that fly.






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






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






18. 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.






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






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






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






23. A glider designed for sustained flight.






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






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






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






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






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






29. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






40. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






50. Aircraft speeds between Mach 5 and 10.
