Find the Optimal Size of a partiallysubmerged cylinder, with a userspecified Cargo applied at the deck.
This simple utility combines the entire design problem into ONE routine. The optimizer not only achieves Archimedean equilibrium, but it also varies the dimensions of the buoy to generate an optimal (lightest by material mass) buoy design. All of the work of designing the buoy, and ensuring the buoy Floats and is Structurally Sound, is performed by the model, and becomes a fullyintegrated cost function. The cost function model is then subjected to (Equality) constraints for Archimedean balance, and (Inequality) constraints to ensure the deck is not submerged. To use this applet:
