>>12976991Force exerted by most mechanisms, hydraulics, muscle, etc., is a function of cross-sectional area. This includes ground pressure exerted by the footprint of the object. Mass corresponds directly with volume. Increasing the size of something, keeping all proportions the same, areas will increase as the square to the multiplier, while mass will increase as the cube to the multiplier.
In scaling something up, mass will exceed any forces its muscles/mechanism could exert.
