¿Por Qué los Trenes No Tienen Volante?

In this video, we explore why trains don't have steering wheels and yet they navigate curves on their own, without anyone directing them. Although it seems impossible, the answer lies in the slightly conical shape of the wheels, which keeps the train centered on the rails and allows it to negotiate curves automatically. Behind this invisible geometry lies a fascinating explanation of physics, mechanics, self-centering, and railway engineering. At Nexo Curioso, we uncover the hidden ideas behind the things we see every day. Subscribe for more videos about science, technology, engineering, and real-world curiosities.
