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






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






3. Robotic aircraft - used extensively by the military.






4. The ratio of inertial forces to viscous forces.






5. 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.






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






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






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






9. 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.






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






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






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






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






14. Design machines that fly.






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






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






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






18. 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.






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






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






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






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






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






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






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






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






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






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






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






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






31. The capability of an aircraft to respond to your flight inputs - especially with regard to attitude and flight path.






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






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






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






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






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






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






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






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






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






41. Aircraft speeds between Mach 1 and 5.






42. Aircraft speeds between Mach 10 and 25.






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






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






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






46. 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.






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






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






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






50. To set or thrust in motion.
