Abstract: Bicoupled Planetary Transmissions composed of any variable Transmission and a planetary gear can be designed to realize any optional speed ratio range including speed reversal and its output ...

Abstract: Sources of biomass fuels for engines are compared to other synfuels. Biomass can be converted to gaseous and liquid engine fuels by the same processes utilized for coal conversion such as ...

Abstract: Involute spline couplings are commonly used in aircraft to transmit power to gearboxes, generators, pumps, and other engine driven accessories. Spline driven accessories which are cantilever mounted ...

Abstract: Based on the elastic interaction between a solute atom and a tensile crack-tip stress field, a mechanism of stress-corrosion cracking was proposed and analyzed. This elastic interaction provides ...

Abstract: An experimental and analytical investigation was undertaken to study the fundamental factors of crack propagation in a thin metal sheet under repeated axial loading. Sheet specimens of 2024-T3 ...

Abstract: This paper supplements a former one with corrections and additional matter. A few changes are made in the Fritz epochs of ?probable maxima? of sun spots, dating from 300 A.D., and it is shown that the frequency distribution ...

Abstract: This paper presents an approach for determining the economic feasibility of refuse-derived fuel production and the recovery of various materials. The information presented here is based largely ...

Abstract: Using the saturation of hysteresis energy absorption as a criterion for fatigue crack propagation, the rate of crack propagation in a thin and wide metal sheet under repeated axial loading is ...
