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 outline shape of a wing when viewed from above.






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






3. Aircraft speeds between Mach 10 and 25.






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






5. Robotic aircraft - used extensively by the military.






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






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






8. The ratio of inertial forces to viscous forces.






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






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






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






13. Design machines that fly.






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






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






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






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






18. To set or thrust in motion.






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






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






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






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






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






24. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






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






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






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






38. Aircraft speeds under Mach 1.






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






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






41. The movement about the vertical axis produced by the rudder and controlled by pedals.






42. 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.






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






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






47. 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.






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






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






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