We consider an example in which one of the 5 applied forces lies inside the convex hull formed by the points where the forces are applied. A strut net that supports such forces and avoids the obstacle represented by the gray circle is the one connecting the points pairwise. The movie shows how each elementary loop forming such a net can be replaced by an open strut net . In agreement with Theorem 1 of Section 2, the reduction can be done until at most 2 remaining elementary loops remain, as shown in the last frame of the movie.
