Wouter, is there a formula to calcualte the weight of a mast (lets make it a uniform tube) based on the tip weight; I can work out a rough approximation based un the summation of torques at points along the tube but that will not be accurate enough for some....
I'm not Wouter, but the answer is no.
A tip weight of 10.5kg could either be an 11 kg mast (1 kg extrusion with a 10kg weight at end) or a 21kg mast with a constant weight throughout, or for that matter a 1T mast with most of the weight at the base.
