I'm sorry if my over-simplified example wasn't detailled enough for you. Maybe you can add some lengthy equations here so you feel better?

Still, I got your point though Mike. Either way, it doesn't matter what total weight is. As mentioned before, what matters is distribution of weight. Thin shaft + thicker head frame = higher BP whilst thick shaft + thinner head frame = more balanced BP.

Anyway, I've sort of become addicted to head heaviness now. Maybe I just like punishing myself, but I really want Victor to release an ultra head heavy MX80 now. Otherwise no lie, I'll design and produce my own. I already have some very cool ideas to implement and the most bad ass racket paintwork design (by me) that you'll have seen on a racket yet!

Maybe I'm taking your comment out of context, but total weight does matter quite a bit, particularly when you start going too heavy or too light. I have a 6U racket which is head heavy and I find it hard to generate a lot of power with it. Probably mostly "bad" technique on my part, but still...

Lol, I meant if the difference was only 2-3g (the difference between the rackets discussed above). Obviously if the difference is greater than it would affect things. Much harder to swing around something heavy than light. Unless of course the 90g racket was head light and the 85g racket was ultra head heavy. Willing to bet that the 85g racket would feel heavier to use.

Yes, for example, sometimes there's only a difference of 1g between a 3U and 4U.

There is one way how 2 rackets with same bp and wt can swing differently, as we stated above, from different mass distribution. But how?

Well, here's how. If one racket were heavier in the middle (ie the shaft) while the other was heavier at both ends (ie head and handle), but both weighing the same with the same bp, then it's obvious that the latter one will swing head heavier.

Sounds about right

Yep, the latter will have a greater polar moment of inertia due to it's weight being distributed more towards the ends, and as such is harder to rotate.

Man, this thread should be called the 'Ego fans club' thread!

Naim, what you need is......a.........FrankenMeteor!

2 packets of Victor lead weights, go crazy.

Actually, might try it! Lol. Was waiting on your review of the FrankenSword first. Want to wait and see if it affects speed, aerodynamics etc.

[jump-smash]

ok I get it
thanks to Maklike and Visor for the explanation
although I've thought of the answer earlier but I kinda doubt myself
but confirmation from you guys make sure that it's really about mass distribution after all

[Yoppy]

But how can 2 racket with identical weight have the same BP if one is heavier toward the top on the head and the other on the lower part of the head?? That can't be the case. The 1st racket will have a higher BP.

[Yoppy]

The critical mass will also affect BP directly

this very thought here got me doubting myself earlier ...
now I'm beginning to feel confuse again ...

I think it's a bit incorrect to think that the weight distribution in a racket is an easy thing to comprehend. We really don't have any idea what's going on under the surface - especially in the handle.

The other thing to consider when talking about 'feel', is that you hold the rackets handle, so what you're feeling doesn't really involve any of the weight of the handle. It's there and it does make a minute difference, but it would be statistically irrelevent I reckon.

Speaking of weird stuff; can someone tell me how the MX80 can be literally the stiffest racket I've held (aside from the Ti550 VS) and yet it plays without any of the negatives for an intermediate like me? I'm dumbfounded. I'm supposed to hate stiff rackets.

I asked myself the same thing. I think because of the aerodynamics of the frame and the woven graphite, you get that speed and stability you don't always find in other rackets, which sort of compensates for the stiffness. A flexible shaft adds a sort of trampoline like flick to swings, but this can be a burden if you're swinging very fast, as it can affect shot angles once the flex corrects itself (straightens). The MX80 is such a fast racket, that you're nearly always swinging at optimum speed, so imo a stiffer shaft helps maintain control and precision.

Also, one other thing, if you check the string bed, you'll notice that because of the 80 grommet system, it has a larger sweet spot than other rackets. The space at the top and bottom of the strings where there is no string crossing has been reduced.

It's not that hard to understand polar moment of inertia.

ooOOoo

OooooO

If you consider these two rods above, they both weigh the same with the same bp (ie centre of gravity). But the first one has a lower polar moment of inertia while the second has a higher one. The first will be easier to rotate around the z axis, while the second will be harder as the mass distribution at the ends will resist rotation.

If you like driving cars, you'll understand this concept when comparing mid engine cars vs front engine cars.

[Yoppy]

OK, so in order to keep the BP constant, the weight is shifted both ways; one to the top and the other to the handle. That makes sense. Does this means that the wood played important part? I always thought they relatively weight the same for the same size.
