Homework and RISA!!

Spent a lot of the day puzzling over trusses.I was able to get a PDF file from someone in my Statics class, so looking through that has been helpful. I also attended another lecture in statics that introduced shear and moment diagrams. The similar triangles method confused me and I actually felt more comfortable understanding the calculus integration method. We were also introduced to RISA today which was awesome. Ive been very much looking forward to it. Its an extremely useful program that is relatively simple to learn. You can make structures of any kind and put all sorts of loads on it. Had you told me that three weeks ago I would have been fascinated. Now I'm ecstatic about the prospects of this program.
