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






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






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






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






5. Aircraft speeds under Mach 1.






6. Design machines that fly.






7. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






15. 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.






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






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






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






19. 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.






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






21. A glider designed for sustained flight.






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






23. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






46. To set or thrust in motion.






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






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






49. 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.






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