rope drum

According to the analysis of friction of rope wraping stump, it makes farther explanation normal stress is the only factor in the judging of maximum static friction (or sliding friction force) under the circumstances of definite friction.

通过对绕桩绳索摩擦力的分析,进一步说明在摩擦系数一定的情况下,正压力是决定最大静摩擦力(或滑动摩擦力)的唯一因素。
