Deflection in cable
Deflection in cable
(OP)
I have a 1/8" dia cable fixed at two ends (same level). A point load is applied in middle. What equation can be used to find how much cable will deflect. I saw some ref but they want two of these three quantities be known 1) Horz comp of tension in cable , 2) load 3) deflection. What If I know only applied load and span and than parameters of cable. Thx a lot.

Also, check on the modulus of elasticity for cable- it's different than for, say, a solid bar.

Option 2, you can find a computer program that handles cables.
Option 3, you can experiment with a piece of the cable.

Please correct me if I am wrong.

Ciao.

1st) If you know the length of cable and span and cable self weight, calculate the tension in the cable without the point load.
2nd) Calculate the tension in a cable with an additonal free hanging length in the middle whose self weight equals that of the point load. Where, your span is the horizontal distance of the outer two portions.
Felt like a million bucks, when I figured this out--on my own.
Take that "Structurals"
