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






2. Design machines that fly.






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






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






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






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






7. 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.






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






9. 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.






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






11. Aircraft speeds between Mach 10 and 25.






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






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






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






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






16. Aircraft speeds under Mach 1.






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






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






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






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






21. Robotic aircraft - used extensively by the military.






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






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






24. Aircraft speeds between Mach 1 and 5.






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






26. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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 ratio of inertial forces to viscous forces.






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






39. A glider designed for sustained flight.






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






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






42. 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.






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






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






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






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






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






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






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






50. 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.
