Consider geometrically similar animals of different linear size, L. Assume that the distance an animal can jump, H, is a function of L, the average density ρ, the average muscle stress σ (that is, muscle force over leg cross-sectional area), and the gravitational constant g. (a) Find a nondimensional functional expression for H. (b) In Swift’s Gulliver’s Travels, the Lilliputians were a race of very small people, tiny compared to Gulliver’s size. If the Lilliputians had the same ρ and σ as Gulliver, what conclusions can you draw on dimensional grounds? Would they jump higher than Gulliver? The same height as Gulliver? Lower than Gulliver?
