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






2. Robotic aircraft - used extensively by the military.






3. The ratio of inertial forces to viscous forces.






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






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






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






7. Aircraft speeds between Mach 5 and 10.






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






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






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






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






12. Aircraft speeds between Mach 10 and 25.






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






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






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






16. Aircraft speeds between Mach 1 and 5.






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






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






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






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






21. 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.






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






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






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






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






26. 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.






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






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






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






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






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






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






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






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






35. 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.






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






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






38. A vehicle - missile - or aircraft which obtains thrust by the reaction to the ejection of fast moving exhaust from within a rocket engine.






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






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






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






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






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






44. To set or thrust in motion.






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






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






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






48. A glider designed for sustained flight.






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






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