Wheelchair tire rolling resistance and fatigue
The Journal of Rehabilitation Research and Development, 1985 The hysteresis loss theory of rolling resistance is developed for solid rubber wheelchair tires. The analysis is used to correlate test data for a clay-filled natural rubber and a polyurethane tire material. A discussion of tire rolling work, hysteresis loss factor measurement, and rolling loss measurement is presented.

On Rolling Resistance of Bicycle Tyres
, 2022 This paper describes a method that enables comparative rolling resistance measurements of bicycle tyres on different road surfaces. The test equipment is a one degree of freedom two-wheeled pendulum with a rigidly coupled eccentric weight. Derived from the conversion of potential energy into dissipated heat by means of rolling resistance losses the ...

The Rattling of Euler's Disk [PDF]
, 2006 The motion of a disk spinning on a horizontal surface has drawn a great deal of interest recently. The objectives of the researches are to find out what produces an increasing rattling sound and why the spinning ends so abruptly.

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy
Advanced Engineering Materials, EarlyView.An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.

The effect of rolling resistance on people’s willingness to cycle during wintertime
Journal of Infrastructure Preservation and Resilience, 2021 Harsh winters reduce utilitarian cycling in many cities. Using an online survey, we examined how increasing rolling resistance due to snow and ice affect people’s cycling willingness.
