[TowerTalk] Dimensions of a tower concrete base

Hi Bob,

Thanks for your reply. Yes, I think you missed the point. Sorry! I'm talking
about the concept in principle not if the total weight is exactly the same.
According to the experts, the weight of the base has very little to do with
the support of the structure. The weight only makes up for about 10% of the
forces needed to support a given structure. 90% or so comes from the
soil/dirt/sand enclosing the base. I'm not an expert in structural
engineering and can't probably explain this properly.

Anyway, back to my question - in principle is there a difference in
force/strength to support a structure if the base is deeeper or shallower
having basically the same weight and volume?

73 Bert, VE3OBU

The last time I looked, 3x3x6=54 and 4x4x4=64 so 64 will weigh more than 54
will.  Am I missing something?
