Hi Sandy
My (albeit simplistic) understanding is that a heavier weight on a short shaft near the axis will have less “flex” that a reduced weight on a longer shaft.
My analogy is that it’s a bit like trying to lift a heavy object with a fully extended arm versus lifting the same object with your arm close to your body.
I’m sure our Mech Eng’s and gifted mathematicians can provide a more comprehensive answer.
Cheers
Dennis
