Math is math. Buy a couple of the cheapest ones you can find for each subject. There are plenty of web sites, like Wolfram, that will do the math for you so you can self score your study.My college maths books are long gone. Recommendations? I'm a bit rusty.
Do not know about them being the same, but it is customary to leave the original author's name in place if much of the content is kept while the new authors make substantial new contribution... If it has become the go-to mechanics of materials text, it should be a big help with all of structural understanding.Isn't "mechanics of Materials" by Gere / Goodno is the same as the Gere / Timoshenko book?
Yes, yes and yes! There are ways to deal with all the issues you mention, a suitable book being a great start, as with many other technical issues. This usually works out quicker, cheaper and easier than doing your own research. I did buy the 1st edition, it likely has 90% of the info of the 2nd edition, but at 10% of the cost. 10 x 90% = 900%. My dollar teaches me much more if it isn't buying the bleeding edge.What I do not know about Polyprop, would fill a book....This I do know ....the cheap Polyprop rope they had at the airport for a while was horrible after about a year. It splintered and was stiff. Poor UV resistance I would guess. I also think it is very hard to glue because it is so slippery.
