Motor de balancín

El mecanismo impulsor es la manivela AB que forma parte del triángulo ABC. La barra FJ actúa como balancín alrededor de E y el triángulo EJL transmite el movimiento al pistón en L.

Usa la aplicación y responde:

a) ¿A cuál de los cuatro modelos iniciales se parece el triángulo ABC?

b) ¿Y el EJL?
