Hey, In 3 months I will officially be a mechanical engineer. However there are some things that my university did not clarify enough. Mostly because some of our books aren't well written. I have some subjects, which I think I should know more about. So as preparation to my first job, I would like to educate myself a bit more. What I'm searching for in the following questions is a recommendation for a good book, a site or a program which clarifies/solves each specific problem. The cost of the books is not a real factor for me, as long as it is a good book . I can read English, German and Dutch. Questions about mechanical design: a good book about force calculation (in a gearbox). e.g. diametersize of the shafts?, how many bolts and what size do I need to seal a flange?, ... a good program about force calculation (in a gearbox). Answer: SIMPACK, Kissoft, ... ? How to chose the best material for your application? Material science book? I know enough about materials, but there's a difference between knowing and actually choosing them. Is there a guideline for this? How to chose the best electrical motor? e.g. with or without gearbox, induction, ... ? Is there a guideline for this? Electromotor book? An overview and clarification about all the types of norms: e.g. EN ISO DIN, ... Introduction to CAM How to determine the tolerances in a design? A good book about tribology in mechanical design. A book about plastic molding What's a good magazine/blog/forum to read to be up to date in mechanical/production design (other then the mechanical design forum)? Are there any other subjects that most beginning engineers don't know, which would be handy? Any suggestions? I hope this is the right place to ask these questions. If you want I can also put each question in a separate thread? Thank you!
