To accept change and wonder of the future while keeping the brilliance of the past, post a big problem to all in the field. The group is tasked to show a hydraulic system with most of the modern technologies at hand while still showing the basics of the geniuses of the past. The task of the group is to show in much detail our example of a hydraulic system for which in this case is the braking system of a Boeing-737. The group is to show the basic mechanism of a simple hydraulic system and on the principles which made it available today. The group will explain and show the different components of a hydraulic system, types of fluids, primary and secondary parts and uses, precautions and so on. And lastly the
