1) To calculate the weight of wire rope (KG/100m)
Formula: M=K X D X D
M=Reference weight of wire rope (KG/100m)
K = certain coefficient of weight (different coefficient for different rope construction)
D = diameter of wire rope
For instance
Wire rope: 6X7-FC -10mm (Nature fiber core), as we know its K=0.351, and the reference weight = 0.351X10X10 = 35.1 (KG/100m)
2) To calculate the wire rope minimum breaking load(KN)
Formula: F = (K X D X D X R) / 1000
F = wire rope minimum breaking load by actual test (KN)
K = certain coefficient of weight (different coefficient for different rope construction)
D = diameter of wire rope
R = tensile strength of wire rope (MPA)
For instance
Wire rope: 7X7-10mm, as we know K=0.359, R=1770, and the minimum breaking load F = (0.359X10X10X1770)/1000=63.5 KN
