对一端固定于光滑球面上的铁链进行受力分析,确定静止稳定后的铁链一端所受固定点的拉力,并将解决问题的方法作一推广,分析条件改变时将铁链固定于光滑曲面所需要的拉力大小. The one-end fixed to the smooth spherical surface of the force analysis of the chain to determine the static stability of the end of the chain received by a fixed point of tension and to solve the problem of making a promotion, the analysis of the conditions change will be fixed to a smooth iron chain Tension required for the size of the surface.
