If the force by the plane on the sphere is also zero, then the expression for \(P\) is \(\frac{0}{0}=\boxed{1}\)

Simple

Yes, and \(\pi=e\).

The analogy to this is that if you have a taut straight wire stretched between two fixed points, any force applied to the wire at about the center of it and at right angles to it will generate infinite tensile strain in the wire. Hence, universes can implode. See Calvin Lin

Sup Michael!

What's a taut straight wire? Oh, and I think your TeX needs some FeXing

I'ma go check out that link real quick - oh wait where'd it go :O and what about the universe exploding and all that

As for the wire example, the moment it stretches by any amount, there is no longer any "infinite tensile strain"---if it should stretch even by one atomic length.

By the way, it might interest you that most of big bolts and screws are manufactured with "toggle-action cold heading machines", which operates on this principle in reverse. That is, there is a ram with a knuckle, so that when a force is applied on this knuckle, it achieves maximum ram force when the ram is straight. Also, there was the time I persuaded a cranky horse up in the mountains to move by tying the rope to a tree and then pushing on the rope. I think the horse was surprised that I was able to move him.
