In order to find the important information of a huge ship, people plan to cut the ship into pieces. They set up many thin strings（线） across the river, the strings quietly cut the steel ship into pieces as if the ship was soft tofu! Is it possible to cut ships with thin strings in real life?

This is because the thin strings have a very small contact area（压强） when they cut things. In the program, the strings are as thin as human hair. To cut the ship, the pressure needs to be 200 MPa. How strong is that pressure? 　Imagine an elephant standing on a string!　 In real life, scientists won’t be able to make such thin strings that wouldn’t easily break, at least for years to come.
