Calculating the force at a single point of contact

AI Thread Summary
The discussion centers on determining whether a chrome wire can withstand a force of 2 N applied at a single point of contact. The chrome wire has a diameter of 0.5 mm and a tensile strength of 600 N/mm², resulting in a tensile capacity of approximately 118 N, which is significantly higher than the 2 N force. This indicates that the chrome wire can easily support the fishing line under tension. Concerns are raised about the potential for the wire to cut the fishing line rather than failing under the applied force. Overall, the calculations confirm that the chrome wire is adequate for the task.

Hi all

May be someone can help me with this problem.

There is a isa-chrome60 wire (d=0.5 mm, tensile strength=600 N/mm^2) which is held at both ends using end connectors ( length of the wire = 20mm). And there is a nylon wire (d=0.5 mm) which is under tension (because of torsion spring) and it is held by chrome wire at a single point. Say the force acting on the fishing line is 2 N. I would like to know if it would be possible to know that the chrome wire could withstand this much of force or not?
Is there any mathematical way to do that?

Thanks in advance.

There is a isa-chrome60 wire (d=0.5 mm, tensile strength=600 N/mm^2) which is held at both ends using end connectors ( length of the wire = 20mm). And there is a nylon wire (d=0.5 mm) which is under tension (because of torsion spring) and it is held by chrome wire at a single point.

Just on those figures,
the cross sectional area of the chrome wire is pi * .25 * .25 = 0.196 sq mm
So the tensile strength should be 600 * 0.196 or 118 N
This is about the weight of 11 Kg.

2 N is about the weight of 200 grams.

So, yes the wire should easily hold the fishing line in a straight line and even applying a force at almost right angles is more likely to break the fishing line than the wire.

As we discussed elsewhere, the wire may cut the fishing line, though.
 
Thanks again vk6kro..
I had done similar calculations, but wanted to confirm if it was the right way. I thought some tensor matrix might get involved.

Thanks and Regards

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
Thread 'What's the most likely cause for this carbon seal crack?'
We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
