Hi, I want to use a hydraulic cylinder to move another hydraulic cylinder but I don't want moving the 2nd cylinder to as easily move the 1st (doesnt have to be impossible, just harder). The system would be light duty and using large or heavy components wouldn't be appropriate. If there is some...

Hi I have attached an image of part of a freely available paper I was reading. It shows the equations for least squares minimization of some equations based on empirical data. I am not completely confident I understand the required steps, and therefore just wanted to talk it through with...

Here's a line from one of my characters "Take too long to aim. Stay close to the holster…and don’t lock yer’ arm. A to B, fastest way between two points is a straight line. Simple physics." I'm confused on whether that's basic physics or geometry. It's in reference to a quick draw like that of a...
