SOLVED:The shells of many mollusks have a spiral design. The chambered nautilus shell is built around a logarithmic spiral, which has the polar equation r=e^θ, where e is a fixed constant that arises in calculus. The value of e is approximately 2.718 . Using this value of e, graph the polar equation r=e^θ. (You may be able to compute powers of e directly on your calculator. If so, you will not need to use an approximation for e .

Logarithmic Spiral Gears https://www.physicsfunshop.com/search?keywords=spiral gears An extreme example of non-circular gear sets. This set is based on the famous Fibonacci spiral and evokes the cross section of nautilus shell with internal chambers. If one gear of this set is turned at constant speed, the other will turn with an varying speed. A laser cut based on 3D prints of Misha Tikh and the research of Balint et al. ➡️ Follow the link above for info on where to get similar gear sets and ot
