A serpentine wall, or crinkle crankle wall, may seem like a surprising structure to use for fences, but may end up being more efficient in terms of building material than a straight fence which must withstand the same horizontal forces. In a post which is the raison d’etre for this one, John D. Cook derives a formula for computing the arc length of a sinusoidal curve . By assuming that such a sinusoidally-shaped wall could withstand lateral forces as much as a straight wall would, had the straight wall been twice as thick, he shows that you could save bricks in fencing off the same perimeter w
