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






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






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






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






5. Aircraft speeds between Mach 5 and 10.






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






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






8. 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.






9. 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.






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






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






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






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






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






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






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






17. To set or thrust in motion.






18. A powered - aerial vehicle that does not carry a human operator - uses aerodynamic forces to provide vehicle lift - can fly autonomously or be piloted remotely - can be expendable or recoverable - and can carry a lethal or nonlethal payload.






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






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






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






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






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






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






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






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






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






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






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






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






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






32. The ratio of inertial forces to viscous forces.






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






34. Aircraft speeds between Mach 10 and 25.






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






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






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






38. Aircraft speeds between Mach 1 and 5.






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






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






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






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






43. Aircraft speeds under Mach 1.






44. 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.






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






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






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






48. Robotic aircraft - used extensively by the military.






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






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