(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement and attempt at solution

Given the matrix S_ij and a_i evaluate a),b),c),d) and e)

For a) I think i use Einsteins convention.

b) I just first sum on i, and then on j giving me 9 terms. The answer I get is 24.

d) can i change m with i since they are both dummy indexes?

e) the same problem as d I guess, is this allowed?

I'm trying to learn continuum mechanics by my self, and this is the first step.

Thank you.
