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






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






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






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






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






6. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






15. Aircraft speeds between Mach 10 and 25.






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






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. To set or thrust in motion.






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






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






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






22. A glider designed for sustained flight.






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






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






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






26. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






43. 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.






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






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






46. 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.






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






48. The ratio of inertial forces to viscous forces.






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






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