如果绳子的一端系在杆子上,而另一端被拉着,挂钩可能会打滑,也可能会被拉得很紧。在本文中,我们提出了一种预测将发生的方法。挂钩的拓扑结构决定了一个不等式,该不等式涉及绳索和杆的摩擦系数特性。如果满足这个不等式,牵引装置的不同圈会相互挤压,并挤压在杆上,从而产生一个自锁单元,可以承受任意强的拉力。
If one end of a rope is tied to a pole and the other end is pulled, the hitch may slip or it may hold fast. In this paper, we present a method of predicting which will happen. The topology of the hitch determines an inequality involving the coefficients of friction characteristic of the rope and pole. If this inequality is satisfied, the different turns of the hitch press on each other, and on the pole, to produce a self‐locking unit that can withstand an arbitrarily strong pull.
