Books?

A point of interest last week, among other things, was some of the reading I was able to do about hydraulics. I knew some hydraulic stuff is going to be coming up and I wanted to get ahead. After watching the lethal strike I continued my reading in the heavy duty truck systems textbook. I studied about the basic concepts of a system and incorporated the mathematical requirements in square inches of the f pump and the cylinder. It's basic math! But to get an idea of what's all needs within a system was good to know. B
