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. Aircraft speeds between Mach 5 and 10.






2. Design machines that fly.






3. The ratio of inertial forces to viscous forces.






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






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






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






7. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






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






20. Aircraft speeds between Mach 1 and 5.






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






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






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






24. Robotic aircraft - used extensively by the military.






25. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






41. 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.






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






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






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






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






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






47. 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.






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






49. The angle formed by the wing chord line and the relative wind.






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