Multiple-wheel all-terrain vehicles without a steering system must use great amounts of power when skid steering. Skid steering is modeled with emphasis put on the ground contact forces of the wheels according to the mass distribution of the vehicle. To increase steering efficiency, it is possible to modify the distribution of the normal contact forces on the wheels. This paper focuses on two a...
Cement concrete and other cement-based composites find wide application in the construction industry. The manufacturing of cement releases a large amount CO2, so use has become major area environmental concern. Attempts have been made to minimize quantity con- crete by replacing it with supplementary cementitious materials. Geopolymer is one those potential candidates for alternative mate- rial...
In this study the impact of production work on the skid roads that have been carried out for many years by manpower animal power or machinery in a beech (Fagus orientalis Lipsky) stand have been examined.
