Uncertanity in angular momentum

[photonqau]

The uncertanity in two components of angular momentum in quantum mechanics is propotional to the third component. What is the physical picture of this result.

I think u want to ask that the product of uncertanity in two components of angular momentum is greater then or equals to the average value of the third component. As long as I know. it has got something to do with the commutation relation of two components of agular momentum. I can't imagin any physical picture of this result , but it will be interesting if anyone have.
