The maximum contact angle at the rim of a heavy floating disk.
We give a simple mathematical argument that as the weight of a floating disk is gradually increased, the maximum contact angle at its sharp rim which is attained before the disk sinks is greater than 90 degrees, and present numerical results which support this conclusion.
