A 32 N weight and an 18 N weight hang from the ends of a string placed over a pulley. The 32 N weight is initially lifted up so that when the system is released it will fall down while the 18 N weight moves up. Assume the pulley is frictionless and that the pulley and string are massless. Find the tension in the string.

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · 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, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
