Boeing 747-100 as illustrated was at cruise when the outer right engine shuts down. This generates a moment that must be counteracted to avoid spinning the aircraft. The pilot could generate an opposite moment by turning the rudder. They could also increase the remaining engines to max thrust. Note: the aircraft would not be in equilibrium in the forward direction ( E F#0). Ignore the extra drag of the shutdown engine. Discuss how much side force the rudder must produce, and what other actions the pilot should do to keep the plane in equilibrium? Drag (Assume it is at the CG) = 35000 lbs Engine Thrust before shutdown = 8750 lbs Max Cruise Engine Thrust = 10000 lbs Total Wing Lift (Assume it is at the CG) = 500000 lbs Make sure you understand the issues with an engine-out emergency related to equilibrium of a rigid body. Write a MATLAB script that solves for the rudder-side force given each engine's thrust percentage setting. The script should also calculate the sum of the forces and moments about the center of gravity. Use this script to investigate various possible actions by the pilot. You will upload your .m-file script in the next Canvas activity.
