I'm going to report this entire thread to the "suspect noobz" thread and have you all banned. Possibly hustler included.

Math for everyone
10lb(44.5N)x8"(.2m)=9Nm
9Nm/.07m(3")=129N(29lb)
129N929lb)x2"(.05m)= 6.5Nm
6.5Nm/.3m(12")= 21.67N(4.85lb)
First off stop changing the order of the dimensions you imbecile.
44.5N x .2m = 9M at the fulcrum then you convert it back to force at the other end by dividing by the length.
9M/.07m = 129N at the other end applied to the transmission with a 3" height fulcrum.
haha wait i just saw your mistake, EVEN YOUR OWN MATH shows a lower fulcrum requires less imput force to output the same force
anyhow to continue your fail *** work...
in order to output 129N with a .05m fulcrum (2" fulcrum - stock shifter)
you do 129x.05 = 6.5M
6.5M / .3m 21.67N.. in other words you'll only need to push the shifter with 21.67N to get the same output with a 2" tall fulcrum.

Its the 3rd line of the link... how do you not see it?

The symbol for torque is typically τ, the Greek letter tau. When it is called moment, it is commonly denoted M.

Clearly you're an idiot and didnt pay attention to my first calculation. I lowered the fulcrum and extended the top portion of the shifter(lever). The friction is included in the force to move the shifter which for mine was 10 lbs of force. This is so frustrating, please thank me when you actually understand.

Thank you? Your own work shows you're wrong.

No, just use the units of measurments(Nm, ft lbs, ect.)

You missed a key sentence in your review of my calculations....

"Thowing out some arbitrary numbers here."

I've attempted to decipher how you're saying I'm wrong but it's not coming together. You are basing my calculations off actual measurements of the miata shifter when the numbers I used have no actual relevance to the actual size of the miata shifter. I was just demonstrating pinciples.

Right, use an arbitrary unit to confuse everyone, good call, instead of units that can be shown to cancel out.

And last, if I'm so wrong why did Miata Roadster use the same design and principles as what I've described(lowering the fulcrum point and extending the top portion of the shifter) and some how several people say it does exactly what I said it would(shortening the throw(minimally) and shifing with less effort). Crazy how that is....

After some math that comes to about 9Nm for the moment(of the fulcrum) and 29lbs of force on the bottom arm tip to the tranny.

Now, lets make a short shifter so lets legenthen the top of the shifter to 12" from the fulcrum and shorten the bottom to 2".

Cliff notes:
Huster(retard) will not understand this
You can effectivly shorten throw and extend the shifter while lessening effort to go into gear.
See that sentence right there with the typo? That right there is your next mistake

When you lift the fulcrum, it gives you a shorter shift. When you shorten it like you did... it gives you a longer shift. Hell you made it even worse by lengthening the top part too.

Again let me draw you another picture since you still dont get it.

Okay, few things..
1) The travel at the transmission must remain the same, do we agree?
2) Left is LONGER throw at the hand do we agree?
3) Right is SHORTER throw at the hand, do we agree?
4) Left has its fulcrum point LOWER, do we agree?
5) Right has its fulcrum point HIGHER, do we agree?



Honestly dude you're like the blond chick in the mph video.

Yeah, dinglebat we all know that and don't dispute it. Why are you arguing again? Just for the fact of arguing?

Can someone ban this buffoon already?
