A Matter of Mathematics

My bloggy momma oughta dig THIS.
I made mention, in a prior post, of the purchase of a "ball and paddle" thingy, for ...um...nun ya fuckin' bidness, and recieved an odd comment 'bout the sturdiness factor, versus a battery operated replacement.
I disagree with that suggestion, and I'll tell ya why.
It's all 'bout "pressure", and the exertion expended.
One must only be aware of a certain mathematical equation in order to assertain that my choice of "toys" will fit the bill perfectly.
What you need to know: F=force.
What you need to find: A=area.
Formula you need to use: P=F/A.
Substitute some known values:
Calculate the pressure that a 50-kg woman can assert on a stable ass, connected to knees, that are in contact with the floor over a total area of 0.007m 2.
Ok, the formula is correct, but the rest is bullshit.
I do know THIS: Drill some holes in da paddle, with a 1/16th drill bit, spaced in a way that the "F" is distributed evenly, produces some "spankingly", nice results.
Furthermore, the "ball and paddle" thingy only costs a buck.
bwaaaaaaahahaha!!!
