Hello
I am trying to carry out exercise 17 of the book "Guide de mécanique" by M. Fanchon, chapter 8: http://www.fichier-pdf.fr/2014/06/15/guide-de-mecanique-fanchon/guide-de-mecanique-fanchon.pdf
In this one, I have to start by summing the torsors in F, D and then C, right?
For the sum of the torsors in E, I have: 0, 300 sin20 and 300 cos20.
But for F, it is written that the module is unknown.
What to do in this case?
Thanks in advance
Kind regards
Diana
