: lo complicado entiendo es soportar esta presión sin ofrecer juntas o una deformación que produzca la apertura de juntas que permita lamentablemente la entrada de agua...
Es puro equilibrio! (imagina que tu mano es el agua apretando dentro del puño nuestro querido Rolex fuertemente, notas cómo se opone el reloj a tu apretón? hasta que lo rompes si eres Superman Returns
:
a las primeras de cambio (es simplemete una particularidad del material)... Por eso se "calcula" un cristal para que resista sin deformarse a las solicitaciones previstas. Sin embargo la otra "losa" del reloj, la caja, de metal ,puede deformarse mucho más sin romper, el metal aguanta perfectísimamente las tracciones.Se podría entonces no ser tan exigente al dimensionar la caja y dejar que aguante y se deforme.Pero claro, un reloj sumergible si tiene partes que al resistir se deforman, crea la apertura de juntas entre elementos y se fastidió la impermeabilidad, por lo que personalmente me llama mucho más la atención el trabajo y el ingenio en garantizar la impermeabilidad de las juntas que el "meter material" que lo puede hacer "cualquiera".Desde luego el cálculo de cualquier "estructura" es posible matematicamente, y los denominados métodos de elementos finitos, que simulan fraccionar lo que sea en "muchos pedacitos", y a través de hipótesis adecuadas establecer las conexiones (esfuerzos, tensiones) entre los pedacitos, y finalmente hallar ese estado tensional, y a través del conocimento de los materiales (con el hormigón, el acero,etc está "chupado") dimensionar para que aguante!
