Anyone have a standard, regulation, or rule of thumb for how much sandbag counterweight is needed for boom bases and/or truss towers.
(We can calculate CG, tipping angle and force required to topple at different heights but how much is safe/unsafe?)
Backstory... a local "technical person" is insisting that every boom base needs a 25 to 1 weight ratio to be safe (so 500 pounds of sandbags to make a 20 pound S4 safe)
His "formula" does not take into account height, off axis weight etc... so looking for something proper and not just a WAG or "this is how we have always done it
