The Law

In the determination of the law of decrease of torsional oscillations of an iron wire, when the range of oscillation is large in comparison with the palpable limits of elasticity, an equation of the formyn (x + a)= bhas been shown by Dr Peddie (Phil. Mag., July 1894) to give close representation of results where—y = the range of oscillation.x = the number of oscillations since the commencement of observations.n, a, b = quantities, constant for any one experiment, depending on the initial conditions of the experiment and the previous treatment of the wire.

Torsional Oscillations

A sphere executes small-amplitude linear and torsional oscillations in a fluid at rest. The equations of motion of the fluid are solved by the method of successive approximations. Outside the boundary layer, a steady secondary flow is induced in addition to the time-varying motion.
