A commercial airliner with four jet engines, each producing 77 kN of forward thrust, is in a steady, level cruise when engine number 3 suddenly fails. Determine the distance d (measured up or down on the figure) to the resultant of the three remaining engine thrust vectors. Treat this as a two-dimensional problem. The distance d is positive if above the center line of the airplane, negative if below. 77 kN 77 kN 77 KN 2 1 7.0 m 13.8 m 13.8 m 7.0 m
