 Basement floor framing ?

I see nails missing from the hangers, the hangers themselves perhaps undersized, and the wood beam pointing towards your camera should have a column to support it's end since that beam is supporting the floor adjacent to the sunken area. The sunken area itself seems to be supported by the steel I-beam.
A hanger transfers load from joist to beam, not vice versa. I'm referring to the wild idea that someone may have fanthomed that the I-beam was providing support to the wood beam via the sunken joists and hangers nearby.
My guess is that someone didn't want their beautiful space interrupted by a column.
Just my two-bits.

I agree with Marc re: the hangers.
How old is the house? That looks like good quality lumber. The cantilevered beam is only carrying one floor joist that is not resting on the steel I-beam, so it might be alright. We can't see to the right of that.
The basement walls will keep the floor from shifting around latterly, as long as there are proper sills with anchor bolts.
I don't see a top plate where they framed under the beam, so there could be some amateur work there.

A total of 3 joists are not resting on any steel. I wrote up the lack of proper fasteners in the hangers. The anchor bolts were kind of iffy with some not even have nuts on the bolts. The lack of a plate under the beam was really down on my list of worries. Both ends of the beam is visible in the pics from first to last. I couldn't see how that beam was supported to be cantilevered like that, thus my worry about movement.
I had to punt this one unfortunately due to my wife's surgery and trying to get the report out in a timely manner. My wife had some masses removed this morning an I was in the waiting room doing my report. She did well and is starting to recover nicely so at least something went well today.
(sorry back on topic now)

I see the hangers as not an issue. The sunken joists are bearing on the steel beam, not the hangers. The hangers and the wood beam they are attached to are there to prevent lateral movement at the end of the sunken joists.
The other joists that run over the steel beam without touching it are probably (cant see from pics) bearing at their ends. As long as those joists are sized correctly for their span it should be ok from what I can see.
If a joist or two is not touching the beam it could easily be shimmed.

Its ok to cantilever a beam, assuming the beam is sized to carry the load. The hangers should be nailed better and like another poster mentioned, the hangers prevent the beam from rotating.

Thanks John that actually made it a lot easier to picture the situation in my mind and clear it up. Guess I was just a bit foggy.
Marc - Thank you!

Just a thought, The cantilever effect of the beam that we are looking at may be getting help from the sunken floor framing from both hangers and being nailed through the back, also the other joists towards us dont seem to need any help. The cantilevered beam, likely not an issue, also underturmened how much weight the beam can carry on the cantilever.

Sunken floors are fairly out of style around here. On a fire repair here the sunken area had been filled in above. When I got below it blew my mind because I did not see any floor drop above.
