####Sliding/Falling Ladder
The sliding ladder is a classic problem in school mathematics. Depending on the location of the person, the falling trajectory is either an ellipse or a circle (a circle is a special case of an ellipse, of course). Three pencil holes are made on the ladder (1/4, 1/2, 3/4) for tracing part of the curves.
Two designs are provided. The circular sliders can be printed together with the rails. After some physical modeling, one should attempt a proof. Here are some
