On both scales, triangular elements were the most stable. However, structures seem less rigid and more ready to twist on the larger scale. The proportions of the skewers and the garden poles were the same. The linear dimensions of the garden poles are 6 times the size of the corresponding linear dimensions of the skewers. The physical consequences of this are dramatic.
Strength depends on cross-sectional area.
This means garden poles are 36 times as strong as skewers. However, weight depends on volume. Garden poles weigh 216 times as much as skewers. Garden pole structures have to support greater weight for their strength and are therefore more floppy. This effect is exaggerated in cantilevers.
