Composite Solids

This is a pier pole found in my beach house neighborhood in Ocean City. Maryland. The pole itself is to help support the pier, along with all the other poles. The white thing at the top could be for decoration, safety, or so one knows where the pier is if they are walking on it late at night. The white thing at the top is a cone figure, which is connected to the cylindrical pole, creating the geometric idea of a composite solid. Pier poles are used to support the pier, which keeps objects and people above the water. They are also used to tie boats, crab cages, and other water-related things off of. The pier makes them (boats, cages, etc.) easy to get to, and not getting wet by the river/sea water in the process.
