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






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






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






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






5. 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.






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






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






8. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






16. Robotic aircraft - used extensively by the military.






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






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






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






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






21. To set or thrust in motion.






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






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






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






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






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






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






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






29. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






37. Aircraft speeds under Mach 1.






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






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






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






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






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






43. Design machines that fly.






44. Aircraft speeds between Mach 1 and 5.






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






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






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






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






49. A glider designed for sustained flight.






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