Why are commercial tension testing machines so expensive

AI Thread Summary
Commercial tension testing machines are expensive due to their need for high accuracy and reliability in testing materials. The limited market demand results in low sales volume, which drives up costs. Technical specifications vary based on the type of tension testing required, necessitating tailored solutions. A referenced book may provide additional insights into the complexities of these machines. Overall, the combination of precision requirements and low production numbers significantly impacts pricing.

can you perhaps explain in technical detail?

What's a commercial tension testing machine?
 
Others have written books on this subject, so I suspect my explanation (in technical detail) would not be sufficient for this thread. Therefore I attached a book reference that might cover part of your needs. There are several types of tension as well, so if you could supply a technical description of your needs, we might be able to provide a more accurate description of what you require.

thank you for the suggestion, I think I should've have used "technical detail" as I'm not really looking for such broad information. I just would like to hear your opinion on this.
 
They are expensive because they have to be accurate and reliable.
Very few are needed, so very few are sold. The economics of volume is simply not there.

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

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

Thread 'What's the most likely cause for this carbon seal crack?'

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...
