When the steel wire (linear material) having a specific gravity ¥ã (kN/m^3) is suspended vertically, the maximum length that can withstand its own weight is obtained as follows.
(The allowable tensile stress of the steel wire is ¥ò (MPa).)

If the length of the steel wire is L,

¥ò = ¥ã*L

L = ¥ò/¥ã = ¥ò*10^3 (kN/m^2) / ¥ã (kN/m^3)

= 1000*¥ò/¥ã (m)

*** Âü°í¹®Çå[References] ***

L = 1000*¥ò/¥ã
