>>> BlackFriday Basic Machines and How They Work
I borrowed this book from a friend and held on to it for almost six months and in that time I poured over it. It's EXTREMELY useful if you're doing model building or playing with simulators and stuff. I use it with LEGOs and LEGO Mindstorm robotics kits. It taught me ALL SORTS of secrets about motion and principles behind gears and gear-driven mechanisms. Just a great book I highly reccommend it if you're looking for a great reference for basic mechanical devices. I had to buy my own copy to have.
