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






2. The ratio of inertial forces to viscous forces.






3. 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.






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






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






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






7. To set or thrust in motion.






8. A glider designed for sustained flight.






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






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






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






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






13. Aircraft speeds between Mach 1 and 5.






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






15. 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.






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






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






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






19. 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.






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






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






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






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






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






25. 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.






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






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






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






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






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






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






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






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






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






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






36. Aircraft speeds under Mach 1.






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






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






39. Aircraft speeds between Mach 5 and 10.






40. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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