Need some help here :(

Hello,
I need some help in scripting the following scenario:

I just need to know how is it possible to drag a mc that streches/rotates the other movie clip only from one end (which is attached with it) ??

For example, there is a an Object-A, just suppose like a stick which is binded by another object that is a Rope or thread, so that when the user drags the object-A the other object which is binded with the object-A also moves along with it BUT only from one end, not from the other end.

I know its hard to explain for me to you guys, but i hope that someone understands what i basically needs.

I really need some urgent help and response here,
your comments will be very helpful for me.

Regards.
