DESCRIPTION:Julian Noble\, University of Virginia\n\nNewtonian physics impl
ies that running is impossible for sufficiently large animals. There are t
wo main factors that influence this:
\n\n\n1. An animal's strength
/weight ratio decreases with size\, hence a\n sufficiently large
animal will be liable to injury if it attempts\n a gallop.
<
/br>\n\n\n 2. The time required for an animal to move its limbs inc
reases with\n size\, but the time an animal can remain in the ai
r (while running)\n does not scale with linear dimension. Theref
ore there is some size\n beyond which an animal has "run out of
time" and cannot take advantage of a running gait.\n\n\n These aspects o
f the biomechanics of locomotion bear on the interesting\n questions of
determining the speeds of extinct species\, as well as how\n varying gra
vity affects locomotion.\n
