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






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






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






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






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






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






7. 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.






8. Aircraft speeds between Mach 10 and 25.






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






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






11. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






32. Aircraft speeds between Mach 1 and 5.






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






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






35. Design machines that fly.






36. The ratio of inertial forces to viscous forces.






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






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






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






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






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. Robotic aircraft - used extensively by the military.






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






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






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






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






47. To set or thrust in motion.






48. 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.






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






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