Uff, ok, I took apart the rostock here and I measured the T2.5 belt with steel core. I pre-tensioned the 1.48m long belt with force of 190N. Then I needed to increase the force to 280N to make it longer by about 2.5mm (one belt teeth span). That corresponds to elontagion of about 0.02mm per 1 meter of belt and 1 newton of force. The glass core GT2 must be super hight quality to have this constant of about 230nm / 28.57N ≅ 8nm. Sure my measurement is approximate and it is a steel core belt, but the difference is about 3 orders of magnitude!
Three last questions for you. You do not need to answer. I'm putting them here to make you see the problem. I assume you always tie unit to the corresponding constatnt with the hightest priority. Otherwise a lot of parantheses are missing in your picture. Citation from your picture:
Tensile Modulus = 80068 newton/0.00064516 meter²
Belt Elongation = (Belt Span Length x Tensile Load) / Tensile Modulus
I modify the last line of the citation by adding paranteses (I hope you believe it is semantically the same):
Belt Elongation = (Belt Span Length x Tensile Load) / ( Tensile Modulus )
Now I replace string Tensile Modulus with its right hand side from the first line of the citation:
Belt Elongation = (Belt Span Length x Tensile Load) / ( 80068 newton/0.00064516 meter² )
Another citation from your picture:
Belt Elongation = (Belt Span Length x Tensile Load) / 80068 newton/0.00064516 meter²
Do you think the last two bold lines of this post are semantically the same?
