One of the fundamental laws of architecture is the force of gravity; the attraction to the ground. What could be a restriction becomes a source of solutions if the properties and physical laws of materials are known. 

In this exercise, the students of the 1st year of Architecture had to make a structure from which they hung ropes that form catenaries. To do this, these ropes only had to support their own weight. This project It was done as a complement to an exercise they had done previously.
