Strangly there is no limiting of the speed which has a far influence on the energy than mass. I suspect the inforcement is much easier with weight than speed.. Just a thought. BobH.
I thought there
was a limit on speed, 200mph governors being required on turbines?
Either way, the limits are entirely arbitrary, with the only criteria being that a majority of decision makers have concluded "this is unsafe, this is not" with reference to a given limit.
