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






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






4. Aircraft speeds under Mach 1.






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






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






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






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






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






10. Aircraft speeds between Mach 5 and 10.






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






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






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






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






15. Robotic aircraft - used extensively by the military.






16. Design machines that fly.






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






18. To set or thrust in motion.






19. The ratio of inertial forces to viscous forces.






20. Aircraft speeds between Mach 1 and 5.






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






22. A glider designed for sustained flight.






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






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






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






26. 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.






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






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






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






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






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






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






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






34. 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.






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






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






37. 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.






38. 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.






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






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






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






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






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






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






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






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






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






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






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






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