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






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






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






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






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






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






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






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






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






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






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






13. 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.






14. 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.






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






16. Aircraft speeds under Mach 1.






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






18. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






27. 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.






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






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






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






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






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






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






34. Aircraft speeds between Mach 5 and 10.






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






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






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






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






39. Design machines that fly.






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






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






42. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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