Hello guys i downloaded this program stru(). I prove to do one exercise but i will stop when I write the beam and internal constraints. I'm wrong because I come out 15 GDL and 9 GDV. Is impossible because the beam is three and not 5.

GDL= n * 3 ....... where n are the number of beam which in my case am 3

Thank you so much
