Given five bars labeled A, B, C, D and E with their Celsius temperatures shown. On the right is a sixth bar with its temperature of 15.0o C shown. One of the five bars is brought into physical contact with the sixth bar but no heat flows between them. Which of the five bars was brought into contact with the sixth bar?

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].
