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






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






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






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






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






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






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






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






11. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






19. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






28. 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.






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






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






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






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






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






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






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






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






38. Aircraft speeds under Mach 1.






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






40. A glider designed for sustained flight.






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






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






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






44. 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.






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






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






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






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






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






50. Design machines that fly.
