We compared the calculated values (Schwunggewicht berechnet) with the values measured on an Babolat RDC (Schwunggewicht gemessen) and as you can see these are quite close.
If you take into consideration that SW’s measured on different machines differ a lot these values do not differ too much.
OK, could you please kindly provide a formula that does this:
"Then the moment of inertia is calculated from the balance point"
I'm truly interested.
