请英语高手帮帮小弟5!
Since the turning radius R’ is usually large compared with the contact length of the track ,would be small and accordingly may be assumed to be equal to 1.Equation 6.17 can be rewritten as follows:
As a consequence of the shifting of the center of turn,the equivalent moment of turning resistance will have two components:one is the moment of the lateral resistance exerted on the tracks by the ground about 0’ and the other is the moment of the centrifugal force about 0’
Substituting Eq.6.18 into Eq.6.19,the equivalent moment of turning resistance becomes

答案和解析
由于转弯半径R '等,通常比较大,与接触长度的轨道上来,将小,因此可假定等于1 .方程6.17可以改写如下:
作为一个后果,转移中心反过来,相当于目前的转折阻力将有两个组成部分:一个是目前的横向阻力施加轨道由地面约0 '和另一种是暂时的离心部队约0 '
而以eq.6.18到eq.6.19 ,相当于目前的转折成为阻力
