Study the vector diagram. Two vectors added using the tail to tip method. The first drawn north labeled Vector Y = 21 centimeters, the second drawn southeast labeled Vector Z = 75 centimeters, and the sum pointing east labeled Vector X = unknown.

What is the magnitude of vector X?

54 cm
72 cm
5184 cm
5625 cm

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].
