While strolling around NY (New York – Manhatten) I noticed a really pretty donut looking at me. I got really impressed with it’s design and colour set. This donut remembered me my, Advanced Math course back in the days I was studying, where we represented mathematically a torus. I opened my phone and viewed it’s equation without any cost. It was free and imediatly available in wikipedia. For me, one of the most marking human accomplishments in my life time. Everyone knows it! And in some direct or indirect way we use it (our children use it).
When we think of something to sit, we think on something we can rest on. These things are around since forever. However for the same function we have imagined a diverse set of designs that get things done. Every design has it’s advantages and disadvantages, probably material strength will play an important role here. The stronger the legs are the thiner they can be and more weight they can withstand. Bellow are a few representations os seats or tables (why not?) in 2D. Some imagination is important from here on. On my office I have I Rise Legs approach and a side legs design, on my living room I have a more classic straight legs design. Probably during a days work I will view many of these designs and probably you will too. Many reasons will determine the design from cost, function and requirements but I will be focusing on the open legs and straight leg variant. Differences? Maybe many, maybe not…. From intuition I feel that straight legs will be stronger but with 120 Kg on top….
