I noticed a crack in the drywall on my ceiling so i crawled up in the attic and saw that there was a ceiling joist (hope i'm using the right term) that seeemd odd right where the crack was happening. I didn't have my phone to take a picture so in order to avoid crawling up there again i've attempted to draw it out in sketchup the best i could.
The joist is made up of 2 2x6's running East and West where it meets up near a set of 3 2x6's running North and South in the middle. It does not actually attach to the 2x6's running Norht and South nor do the 2 2x6's touch.
It appears to me, even though i don't know my top from bottom on this subject, that there should possibly be a support or wall under this joist but there is nothing under the 2x6's running East/West or the set of 3 2x6's running North/South. Any ideas from fellow mustachians on how to fix this joist or if i even have anything to worry about.
