Main Question or Discussion Point

Here's one for you guys. I've done some research and I couldn't find an exact answer to my question...

In the experiment shown here:

Why is there no standing wave on the segment of the string between the pulley and the mass hanger? I'm guessing it's because the pulley is a fixed node that cannot oscillate? Is there more to it than this?

Yes I believe that the pulley deadens the vibration at that point. Even though it is at a node, and would continue vibration if the pulley was very very small, I think it is big enough to deaden the string that is wrapping around it.
