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 'HP Required to move a robot 10meters at 1.5m/sec'

I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...

Thread 'Calculate minimum RPM to self-balance a CMG on two legs'

Thread 'Calculate minimum RPM to self-balance a CMG on two legs'

Here is a photo of a rough drawing of my apparatus that I have built many times and works. I would like to have a formula to give me the RPM necessary for the gyroscope to balance itself on the two legs (screws). I asked Claude to give me a formula and it gave me the following: Let me calculate the required RPM foreffective stabilization. I'll use the principles of gyroscopicprecession and the moment of inertia. First, let's calculate the keyparameters: 1. Moment of inertia of...

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
