After I found the weight model
And display the effect of variables
The result was illogical
In the attached pictures:
Elements 1, 2, 3, 4 and 5 have the same lengths
Elements 7, 8, 9 and 10 have the same lengths
How do two elements have the same length and the same change in the section? Do not they have the same effect on weight?
Thank you for your help in advance
