Cleft density
« on: May 25, 2020, 04:20:35 PM »
Can someone please enlighten me as to how B3 calculate the density of their clefts? I know the basic idea is mass/volume but what is the unit?

After playing around with the units of a cleft i have come up with the mass as 60.85 ounces and a volume of 0.1431 cubic feet. And the number was 425.3 so i am guessing this must be it

You’re on the right track but 425 is impossibly low density (based on what I recall). But it’s definitely in the 400s so you’re within the ballpark.

Looking at a few of the trott posts people have had clefts under 400 so surely not impossibly low density.

Wasn’t 400 their starting point for an average cleft?

I assume so as im talking about the whole cleft pre-handling and shaping

How is the density calculated?

Kg/m^3, I'd guess

Mass over volume is the formula. Units is the key. The most commonly used metric units for density are kg/cubic meter and when i put the values in the answer was 425.7
Incidentally when i switch to imperial units (cause you know God save the Queen) and calculate with oz/cubic feet the answer is almost the same (425.3) so it must be one of the Two

Exactly? It shouldn't be... On the subject of units, the UK is not America, we may use imperial units on road signs but you won't find them used for actual work.

Corrected to "almost" the same  :D this was a fun excercise for revising high school math. I had forgotten how to calculate area of a triangle

Yeah but we do quote bat weights in pounds and oz don't we???

from memory average density of a cleft was 400

If a shape you liked was 2lb 10 but you wanted 2lb 8 then you could need a lower density - i think a density of 10 was an ounce

favourite shape at 2lb 8 would need a 380

I think this is correct as had a couple of B3 bats under 400, one as low 369.
