I am looking for some advice on using carbon fiber for a project. It's not necessarily about robotics, but I really don't know where else to find answers. My project is to build a holder for a tablet, but the design is remarkably similar to that of a UAV. Basically take the popular UAV design that has a central section with six or eight arms extending outwards, and then imagine placing a tablet on top of it. Then imagine that the central section is connected to the end of an articulating arm or is sitting on the top of a tripod head. In this example, I need to know how to determine how strong the central structure needs to be to support the weight that it will be bearing, as well as the stress placed upon it in holding the extended arms in place. The actual tablet will weigh 1.75 lbs.
