摘要：For the first time in the theory of solid cargo fastening there has been investigated a case when the cargo is in motion in relation to the wagon floor with acceleration, its speed being at this moment equal to speed. There have been set out the results of mathematical description of cargo motion in relation to the wagon. It has been established that the lateral force perceived by the flexible fastening elements in value is smaller than the force obtained when inertia force in relative motion (at rest) is not taken into account. Hence, the cargos displacement crosswise the wagon in this case will be smaller. This, in its turn, will affect the decrease of elongation value and consequently the decrease of the effort of every flexible element, thus increasing their load-carrying capacity.
