| Abstract | The focus is the power formulae relating periodic time in terrestrial locomotion and flight to mass and length. The periodic timing of limbs and wings oscillating comfortably in absolute co-ordination is viewed as the characteristic period τ0 of a system in which the free, undamped oscillatory motion of a point mass m at a distance l from a fixed axis does work against two conservative forces. These forces are in the form of gravitiy g acting on the point mass and a spring of stifffnesss k acting at a distance b from the axis. The system’s characteristic period can be expressed most simply as : τ0=2π[ml2/9mlg + kb2)]1/2. |
