MOTO MATHS: We can work it out ...

[Berwick Boy]

I know it's simple maths ... but in my opinion it's fun.  As a kid, I'd often work out actual
CCs of a bike, when reading bore and stroke in brochures.  I like numbers 
(And apparently we need to do this stuff from this age on, or otherwise it's Sudoku)

No. ONE:
   In November, 1970, a Yamaha RT1 Enduro is cruising highway at 5,700 RPM, and sits on 95 kph.

Question:  How far does it travel (in metres) per single revolution of the crankshaft?

0.2777777778 meters traveled per crank revolution

That would be metre not meter. Just sayin' 

The unit is very important 

Get with it Greg, there is no such thing as an Aussie spell checker

Ask Denny boy and Greggy Holmes if you don't believe me

Yeah, me too,,,,I wish I had a bigger bank account to do it with though;D

That's a good sketch, cracks me up
and I didn't need the spell checker to type that Scrivo

Me too

Measured in pascals(N/m2) how much spring tension(force) does a circlip require to retain a set of Montesa fork dampers

[Mick D]

And I want to see an honest answer up here, by the time I get back from the bottloe

[Snowy 76]

OUCH!!

[Tim754]

Isn't pascals the unit of air pressure? Kilo-pascals, or naa that be a Latin American axe murderer. n/m2 maybe Newton /metres Squaredances.

Sorry it's these great night time Flu pills  6 of um an shites I be feelin bloody finnnnnnne nows                      ..

[HeavenVMX]

Measured in pascals(N/m2) how much spring tension(force) does a circlip require to retain a set of Montesa fork dampers

carried out an RCA on the fork remains to determine what happened. As usual at least three things came together to give the Ohhhh Far...........k moment. If any any of those had been eliminated there would have been no ouch moment.

That crash makes two wacks (or whacks whichever you prefer) on the head in a little over a year, remember the working bee incident   :'( when you craddled my head as I flaked it and fortunately I came too just before you launched into mouth to mouth

To answer your question? ideally for circlip that size about 560 kp/mm² but as low as 480 kp / mm² should do the job

note the unit kilopascal/millimetre² 

The ones in the GP Monty forks appear to have had 1 kp/mm² 

At least I didn't fall (pun intended) for the old I'm completely stuffed so I'll do just one......... more la......p    crash   jokin OK

[Berwick Boy]

Another numerical topic.  If working out historical costs - to see what
it costs in today's money - I use a very rough estimate of doubling the money for every
decade.

IE:  If a DT1 cost $650 in 1970, then I'd double that for every decade

1970  $650
1980  $1300
1990  $2600
2000  $5200
2010  $10,400  (holds fairly true)
2020  $21K   (fails ..?  I don't think a YZF will reach this)

[Mick D]

Bizzzzzzzzzzzzzzzzzzzz, sort of wrong boys :'(

About time you sacked that doctor Tim

We are  governed by the metric system in this country and as a base line for the scientific community, as such "The unit of tension is the same as the basic unit of force" Its one of those ambiguities.

A pascal is a measure of force, pressure or tension per unit area, defined as one newton per square meter, whoops metre .

You will argue all your life long, but the unit of spring tension is correctly measured in pascals. Although because One Pa = one N/m2, you will find that most say for example suspension guys will quote in N/m2.
Nut indeed the Scientific community chooses and does quote spring tension in Pa(Pascals)

Top Fueler needs 120hp to drive the fuel pump and 600hp to drive the blower. Pistons cost $60 each plugs $2

Yeap some stuff we just have to live with , like flipping your bike on the start line some turtles just aren't ever gunna let ya forget  

[HeavenVMX]

I stand corrected. Meter it is! Never liked the way metre was pronounced anyway 
Enjoy your new Maico

[Mick D]

Gee, apologies to your thread with my drivel Berwick Boy

Never liked the way metre was pronounced anyway 
Enjoy your new Maico

Thanks, I am excited to be picking this Maico up tomorrow. Its a beautiful goer

I have never accepted the way the  French Academy of Sciences imposed the their way of spelling Metre upon the rest of us, just because it was their concept, wankers.

Educations vary, even in the same country.
That is what I recalled
Just found this,
Link to Unit of tension

Goodnight
