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






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






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






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






5. Design machines that fly.






6. Aircraft speeds between Mach 5 and 10.






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






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






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






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






11. Robotic aircraft - used extensively by the military.






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






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






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






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






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






17. 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.






18. 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.






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






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






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






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






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






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






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






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






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






28. To set or thrust in motion.






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






30. 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.






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






32. 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.






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






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






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






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






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






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






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






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






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






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






43. 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.






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






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






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






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






48. The ratio of inertial forces to viscous forces.






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






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