For anyone that thinks bike engines have no torque take a look at the picture below


Twisted Axle
This is what a Kawasaki ZX10 (approx 137bhp & 79ft/lbs) will do to a 30mm dia 6mm thick chunk of steel if you get a bit over aggressive with the take offs! Up until last week this was one of my axles on which the sprocket drive is located, I will admit to giving it quite a bit of stick recently but when it finally broke I was being gentle with it. If you look at the keyway you will see it has twisted along its length, fortunately I don't need the keyway so its replacement is of uniform thickness & section & hence substantially stronger.

Imagine what Zetec would do then!

You copy and pasted the url of the picture from the address bar at the top - That won't work - If you look at the bottom there is part of the correct url with image tages either side of it (Where it says Forum Code )

You then need to add http://www.locostbuilders.co.uk to the start of the address after the first [img]

i.e

[ i m g]http://www.locostbuilders.co.uk/upload/twisted axle.JPG[/i m g]

I've put a space between the letters in [IMG] otherwise it would display the picture not show you an example of the url you need to copy and paste!!

Bike engines may have low torque at the crank, but they have something a car engine does not..

Primary Reduction.

A very effective torque multiplier

...and high revs too, which means you can further gear it down and multiply it up

So that's what a gearbox does

I think you know what I mean

Torque multiplication should be on the GCSE Maths syllabus!
