Hi, I'm currently working on a project for a braking system of a carousel. Basically in order to start designing the brake I need to know what the maximum rotational speed of the carousel should be. The max diameter of the surface will be 2 meters and the maximum speed at the periphery should not be greater than 5m/s from standards. However as the diameter gets smaller and smaller the rotational speed will still increase taking these standards. What I want to do is work out the speed that will throw someone off the carousel using maybe the centrifugal force or some such method. I assume that this is most likely on the outside of the circle? (i.e. max radius of 1). I was wondering if anyone had any suggestions as to how I would calculate this? Any help would be greatly appreciated. Mark.
