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. Robotic aircraft - used extensively by the military.






2. 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.






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






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






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






6. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






15. 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.






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






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






18. Aircraft speeds between Mach 1 and 5.






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






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. A short - memorable phrase used in advertising or associated with a political party or group.






22. A glider designed for sustained flight.






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






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






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






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






27. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






38. Aircraft speeds between Mach 10 and 25.






39. 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.






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






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






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






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






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






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






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






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






48. To set or thrust in motion.






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






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