Reference no: EM13314876

A rectangular blade weighing 0.02 lbf is kept in the surface of water (sigma=0.073 N/m) solely by surface tension forces. What is the minimum perimeter of that the blade must have so that this is possible? Approximate the blade to a rectangle, and neglect the internal perimeter in your calculations.
