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

Question

A commercial airliner with four jet engines, each producing 72 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.
