The deformation of a loaded bike tire has been analyzed with a model consisting of a toroid of thin inextensible walls mounted on a central rim. If the tire radius is much smaller than the rim radius, the deflection, d, of the tire can be calculated as a function of the applied load, F. The solution can be approximated by a power law dependence F ∝ d 3 / 2 for small loads. The theoretical predictions compare well with the experiments carried out on two bicycle tires.The deformation of a loaded…

Strategy on choice of layback spins in figure skating

Spin is an important component of figure skating, one of the most elegant events in the Winter Olympic Games. It is always presented as an example of the conservation of angular momentum in mechanics



Contact of an Inflated Toroidal Membrane with a Flat Surface as an Approach to the Tire Deflection Problem

Abstract A finite element procedure has been developed for the displacement and stress analysis of a homogeneous and isotropic inner tube mounted on a rim and in contact with a flat surface. The

Thermodynamic derivations of the mechanical equilibrium conditions for fluid surfaces: Young’s and Laplace’s equations

The fundamental laws governing the mechanical equilibrium of solid-fluid systems were formulated in 1805 and 1806. They are Laplace’s law, which describes the pressure drop across an interface, and
