[net.origins] Weightlifting Ultrasaurs

Ted Holden claims, in his now famous article, that muscular strength is
proportional to muscular cross-section. This is true only if all other
factors are held equal. In this case, the length of the muscle is
different (!). Ignoring structural differences (leverage, different kind
of muscle, all those fudge factors) and using Ted's figures corrected for
length (2 feet for a human thigh, 10 for the beastie) it turns out Dino
needs a radius of  sqrt(36/5), which is something less than 2.7 feet.
(this is gotten by stretching a cylinder 12x2 feet to one of 10 foot length).
Convert to an elliptical cross-section and this figure, while admittedly a
little big, is in the right ball park.
