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






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






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






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






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






6. Design machines that fly.






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






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






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






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






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






12. 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.






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






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






15. 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.






16. Aircraft speeds between Mach 10 and 25.






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






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






19. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






26. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






33. 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.






34. Aircraft speeds under Mach 1.






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






36. To set or thrust in motion.






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






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






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






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






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






42. The ratio of inertial forces to viscous forces.






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






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






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






46. Aircraft speeds between Mach 5 and 10.






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






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






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






50. 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.
