Why is a steel rope made of many wires rather than a round bar of steel?
It is a strand of steel that bends more easily. In general, but the tensile strength is still a single good, but many shares of a broken, will soon be found, easy to change in time, or a broken, immediately out of the accident.
The multi ply, in order to increase the cross-sectional area increases the tension will not suddenly broken, fine wire bend more easily, so the bending of wick core can be better, with better lubrication of steel wire rope. If it is a steel bar, it is not easy to bend, it is easy to break suddenly, and the practicability is poor.
