"How can concrete even float?!"
"Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object."
-Archimedes, Greek Mathematician and Engineer
Archimedes' Principle, developed in 250 B.C.E by the famous engineer, holds true no less today than in antiquity. Ships have been constructed of steel, fiberglass, and other materials more dense than water for hundreds of years. Displaced water exerts a force on the boat, which keeps it afloat if the material is shaped properly. This allows for all manner and sizes of vessels to float - regardless of construction material!
However, for safety purposes we use concrete that is less dense than water. This means that in the event of capsizing, our canoe will remain safely above water level and will not pose a safety or navigational hazard. (The Titanic should have taken notes!) We accomplish this through the use of glass bead aggregates instead of the rock or gravel used in standard concrete. This reduces the density of the overall canoe to less than that of water, so it floats even when filled with water and paddlers!
Our year is divided into separate segments: Design, analysis & testing, construction, quality control, and finishing. Members are encouraged to contribute whenever they can to any phase of the project that interests them – as much or as little time as you want to!
