NIFE Aero Latest Version with Certified Solutions Define Vector A quantity that expresses both magnitude and direction. A vector quantity is represented by an arrow that displays direction and has a length proportional to magnitude Moment Force applied at some distance from an axis or fulcrum F x d (Distance: from the point of rotation that is perpendicular to force, "moment arm") Equilibrium Flight When the sum of all FORCE and all MOMENTS around the COG are equal to zero ...
