>Also, why the dead weight? 500 tons is easily doable with a (smallish) hydraulic press. Sure, but how do you know the hydraulic press is applying 500 tons? You need to have a universal standard for length (to determine the area of your piston) and for force (which doesn't exist), and consider the friction in your hydraulic system. We can generate a universal standard for the kilogram, then duplicate that log(500) times, and create a very well controlled mass that we can hang from stuff. The level of accuracy that is needed would surprise you. |
