Thread: travel distance around Australia

What I can say is that you need to pick the time to cross the Nullabor. We timed it badly and drove the whole distance into a terrible head wind. A few weeks later and we would have had a tail wind and spent about 50% less on fuel for that part of the trip.

Derek,
You should have turned the rig around and done it going backwards then you would have had a tail wind.

Dave.

Circumference of 2∏(r+n) means for every n metres increase in radius the total circumference increase by an additional 2∏n metres.

For what its worth we did just over 25,000km on our trip this year and I don't think it would have mattered which way we went. That included an anti-clockwise tour of Tasmania.

Is that how you drive the semi in windy conditions

Dave.

If he did that everyone would,ve thought he was going the other way.

That would be taking the shortcut judging by the reply's in this thread

I don't pay for fuel and I lost the job a few months ago due to the company being sold and the new owners using there own transport.

I will be looking for a new job next year as SWMBO(the minister of finance) has approved a new puma if I can get another part time job.

Dave.

Some Also say that if you go clockwise by the time you finish your wound up,
But by going the other way you actually un-wind..

and if you go the same way twice you will overwind and break the spring

You are of course correct. Regardless if the road is a perfect circle or a rectangle with radiused corners, the distance will be 2.pi.lc where lc is the difference between the lane centres.

If we assume that is 5 m then the difference works out quite neatly to be pi.10.

However, basic geometry aside, a difference of 31.xx m on a journey of 20000000+ m can be considered negligible, and possibly immeasurable in an actual experiment (i.e. if you got two identical vehicles and actually drove them round in opposite directions.).
