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. To set or thrust in motion.






2. Design machines that fly.






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






4. 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.






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






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






7. Robotic aircraft - used extensively by the military.






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






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






10. 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.






11. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






22. Aircraft speeds under Mach 1.






23. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






30. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






40. Aircraft speeds between Mach 10 and 25.






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






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






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






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






45. A glider designed for sustained flight.






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






47. 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.






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






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






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