We will do that later until it starts to slip and then at that critical angle that it starts to slip you have a value for mu of s for the static friction coefficient. 增加倾斜度直到物体开始下滑,然后记住开始下滑时的角度值,通过公式就能求出,静摩擦系数μ静。
The maximum friction force decreases at first and increases later as the angle of belt cord increases, and the static friction force in ground-contact area is symmetrically distributed; 随着带束层帘线角度的增大,最大摩擦力先减小后增大,静态接地时摩擦力呈对称分布;
