    The force F is created by the reaction of the Earth to the thrust of the rods, whereby the thrust is created by a force of action and reaction.

    Explanation:

    To answer this question, let's write Newton's second law of the two axes

    Y Axis

    Fy + N - W = 0

    Fy + N = W

    X axis

    Fx - fr = 0

    Fx = fr

    The force F is created by the reaction of the Earth to the thrust of the rods, whereby the thrust is created by a force of action and reaction.

    The direction of this force is along the length of the rods that are in an Angle, where the x and y components of the force come from

    In general this force is small because the rubbing of the skis is small
