Today Hi I'll talk about my day. It was a good day I think, I had an exam today of fluids mechanics and it wasn't difficult . Then I practiced welding but I felt a little bad because the firsts try I couldn't do it, only on the tenth try I welded more well :). I want to practice much more because it was an interesting experience so I think I need some books to learn. Do you know a good book for that? An another question, do you know where can I find information about mechanical engineering?
