An investigation on the most effective structure for carrying weights

Abstract
There are many different types of water towers in our current age with different structures. The uses of water tower is to store large amounts of water so that it is an alternative source of water when a state's water supply is being cut off. It can also be a direct source of water for run down villagers without a proper water source. However, some water towers still fail to carry heavy amounts of weights due to its structure. One example was the old water tower that came crashing down from the roof of a building in Chicago's Lakeview neighborhood, injuring three people, on July 31, 2013. An aim of our experiment was to determine the most effective structure for carrying weights. Three different structures, one with a cross design, one with a middle pillar and one with diagonal beams were constructed and tested for the maximum amount of weights it can withhold, along with a combined structure of the three. Results indicated that the individual structures were unable to hold as much weight as the combined structure. The diagonal beam proved to be the strongest among the original structures, carrying a total of 20 kg. However, the final structure was able to hold 35 kg of weight. With many structures combined into one, flaws of each individual original structure was countered and thus was able maximise the amount of weight that it can withhold. With this research, water towers are able to hold more weights/water in a smaller space. It also reduces the chances of structure failure and endangering the lives of many.
