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






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






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






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






6. Aircraft speeds between Mach 5 and 10.






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






8. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






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






20. 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.






21. The ratio of inertial forces to viscous forces.






22. Design machines that fly.






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






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






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






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






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






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






29. 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.






30. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






39. Aircraft speeds between Mach 10 and 25.






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






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






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






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






44. Aircraft speeds under Mach 1.






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






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






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






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






49. A glider designed for sustained flight.






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