The original Graf was 776 feet in length. Take the Graf Zeppelin and its successor note and The Hindenburg's sister ship the Graf Zeppelin ll for example. Sorry, Hotelicopter.Īirships, on the other hand, benefit greatly from the square/cube law, as even small increases in size can quickly increase the volume of buoyant gas they can carry. Helicopters are hit particularly hard by this law the largest payload of a cargo helicopter is about 20 tons, versus the world's largest airplane, with a payload of 275 tons. This applies to flyers as well: Double the size, and you get four times the wingpower attempting to keep eight times the weight airborne, so the creature's ability to fly has actually been cut by half. And Newton's famous Second Law (the "force = mass × acceleration" one) means that if you double a critter's height while keeping it the same shape, you end up with four times the muscle power moving eight times the mass, so instead of having the same relative agility as the original, the double-sized creature actually has only half. The point of this law is that with living beings, strength is (more or less) a function of area (the strength of a muscle or bone is proportional to the area of its cross-section, not to its total volume), but weight is a function of volume. When an object undergoes a proportional increase in size, its new volume is proportional to the cube of the multiplier and its new surface area is proportional to the square of the multiplier.įor example, if you double the size (measured by edge length) of a cube, its surface area is quadrupled (2^2 = 4), and its volume is increased to eight times its original volume (2^3 = 8). A scientific principle often ignored in media:
