I have been working on this problem (trying to understand a topic in an advanced engineering textbook) for 4 days now. Today, you put an end to my 4-day-agony. "see you" in other posts!

I salute and appreciate your help, fresh_42. I take my hat off to you.

Impressive, fresh_42. Could you please suggest one or two good books (or website links) on this subject so that we could refresh ourselves with more exercises? Thanks again. PS. and you did also find an errata in the book (equation 2.4).

Dear forum, I'm new here (living in Arizona). I am stuck getting to derive this: F1−F2−F3 = 0, (2.1) F1c1−F2c2−F3c3 = 0, (2.2) F1z1−F2z2−F3z3 = 0. (2.3) Where the only unknowns are F2 and F3. The textbook states that F1, F2 and F3 can be eliminated to get: c1z3 −c1z2+c2z1 −c2z3 −c3z1 +c2z2 =...
