Mooring line for wind turbine model

AI Thread Summary
A floating wind turbine model is being constructed for a wave tank experiment, requiring a suitable mooring line. The line must exhibit a linear force-elongation relationship at tensions up to 50 kg, minimal elongation over time, flexibility for a pulley system, and corrosion resistance. Options under consideration include monofilament steel wire, carbon fiber wire, and fishing line. Suggestions from participants include using Spectra fibers or thin wire rope commonly found in fishing tackle shops. The discussion focuses on finding the optimal material for the mooring line to meet these specific requirements.

Hello,

I am construction a floating wind turbine model which is going to be used in a wave tank experiment this fall. Currently I'm looking for a mooring line for this model.

The line will go from the wind turbin down to the bassin floor, where it will go through a pulley and back up to the surface. Above water it will be connected to a spring system which models the stiffness of the mooring line.

The mooring line has should have the following characteristics:
- Approximately linear relationship between force and elongation in the area 0-50 kg tension.
- Very little or none elongation with time for a given force (low creep?)
- Be able to be bended of in a pulley of unknown size, angle approximately 100 degrees.
- Good against corrosion.

Does anyone have any tips?

I am currently considering:
- monofilament steel wire
- Carbon fiber wire
- Fishing line


Best regards
Anders S

Specta fibers might work well.
 
Or maybe a thin wire rope like that sold on fishing tackle shops for leader material.

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
