The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r Ć f) Ā· n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, ā5, 4] n, r = [ā3, 5, 2] m, and n = [6, 5, ā7].
