## Steering axle trailers

D-Value = g x

T x R
T + R

where:

**g**= Gravitational acceleration; 9.81 m/s2;

**T**= Technically admissible maximum weight of towing vehicle in tons;**R**= Technically admissible maximum weight of towing vehicle in tons;**D-Value**= Theoretical load for the determination of the theoretical horizontal dynamic force between towing vehicle and steering axle trailer;
