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






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






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






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






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






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






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






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






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






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






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






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






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






14. 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.






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






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






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






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






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






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






23. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






33. Aircraft speeds between Mach 5 and 10.






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






35. The ratio of inertial forces to viscous forces.






36. 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.






37. A glider designed for sustained flight.






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






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






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






41. 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.






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






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






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






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






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






47. To set or thrust in motion.






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






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






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