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






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






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






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






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






6. To set or thrust in motion.






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






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






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






10. 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.






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






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






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






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






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






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






17. 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.






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






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






20. A glider designed for sustained flight.






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






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






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






24. Aircraft speeds under Mach 1.






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






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






27. Aircraft speeds between Mach 5 and 10.






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






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






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






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






32. 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.






33. Aircraft speeds between Mach 10 and 25.






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






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






36. The ratio of inertial forces to viscous forces.






37. 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.






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






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






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






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






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






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






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






45. Aircraft speeds between Mach 1 and 5.






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






47. Design machines that fly.






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






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






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