0/1 pts Question 3 The magnitude of the projection of a force vector along an axis can be found by: Summing the direction cosines for the force w Multiplying the unit vector that represents the axis with the force vector. Taking the dot product of the force and the unit vector which represents the axis. Summing the direction cosines for the axis Taking the cross product of the force and the unit vector that represents the axis.
