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 force caused by the gravitational attraction of the Earth.






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






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






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






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






6. 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.






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






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






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






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






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






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






13. To set or thrust in motion.






14. Aircraft speeds under Mach 1.






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






16. 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.






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






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






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






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






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






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






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






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






25. A glider designed for sustained flight.






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






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






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






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






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






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






32. Aircraft speeds between Mach 5 and 10.






33. The ratio of inertial forces to viscous forces.






34. 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.






35. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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