QUESTION:

A force of \(F = \{6i - 2j + 1k\}\ kN\) produces a moment of \(M_O = \{4i + 5j - 14k\}\ kN \cdot m\) about the origin, point O. If the force acts at a point having an x coordinate of x = 1 m, determine the y and z coordinates. Note: The figure shows F and \(M_O\) in an arbitrary position.
