When band, it is contemplated that the other influences generated on cylindrical body or by the multi-diameter shaft shape solid that cylindrical body forms are dropped as much as possible
To minimum.
Tensioning band outmost turns are acted on by external load device and generate pulling force, external load device to all tensioning bands
The pulling force that outmost turns apply is considered as external force, it is desirable that the multi-diameter shaft that the pulling force of all tensioning bands is formed for cylindrical body or by cylindrical body
Part except the winding area of shape solid, does not generate internal force.So being required to meet following equilibrium condition when arrangement tensioning band.
