Hi,
I'm trying to figure out how long a wire will be when I hang it up between two supports.
I have:
The Young's modulus for the wire (E): 56kN/mm2
The length of the span (L): 55m
The weight of the wire (w): 0.73kg/m
The tension of the wire (T): 11kN
The cross sectional area (A): 266mm2
I know how to calculate the length of an inelastic wire:
L'= L + (w^2*L^3) / (24T^2)
But that I assume the Elasticity of the material must matter?
So, what I'm after is some formula for calculating this, not an answer
(although an answer could be good to compare to I guess)
Regards,
Mattias
