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






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






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






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






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






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






7. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






17. Aircraft speeds between Mach 10 and 25.






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






19. Aircraft speeds between Mach 1 and 5.






20. The ratio of inertial forces to viscous forces.






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






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






23. 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.






24. Design machines that fly.






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






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






27. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






42. Aircraft speeds between Mach 5 and 10.






43. Aircraft speeds under Mach 1.






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






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






46. 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.






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






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






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






50. Robotic aircraft - used extensively by the military.
