1. A commercial airliner with four jet engines, each producing 90 kN of forward thrust, is in a steady, level cruise when engine number 3 suddenly fails. Determine and locate the resultant of the three remaining engine thrust vectors. Treat this as a two- dimensional problem.
2. Determine the x- and y-axis intercepts of the line of action of the resultant of the three loads applied to the gearset.
