The other thread just reminded me of a question I saw many years ago (In New Scientist IIRC)
Consider the situation...
Imagine a string wrapped all the way around the Earths equator.
Now imagine a second string raised to a point 1M above the earths equator.
Q: How much longer is the second string than the first.
I am not searching for the answer here, simply the method.
What was your solution, and how did you arrive at it?
