Engineering mechanics task can anyone solve this?
Hello dear community,
I have a small problem with one of the tasks in my technical mechanics exercise today.
How do I get the -0.035 out of here? I've tried a lot of things and often get -0.021 or -0.046 but never the right result.
I won't ask my professor because he's currently on vacation and won't be available by email until next week.
I hope someone can help me here.
With this formula:
There someone photographed the sacred writing from the Bizeps-Bernd xD
However haha
Thanks for the formula, just have some problems with the meanings of the characters in the formula.
We always had only Sigma X and Sigma Y and Sigma Z, these are Sigma 11,22 and 33, right? If so, what is Sigma ik and the last sign?
Delta ik is the Kronecker Delta, which is simply 1 if i = k, and 0 otherwise. Sigma 11 is the normal voltage in the e1 direction at the plane whose normal vector shows in the e1 direction. A normal voltage in this direction. It may be that they are different from you.
