Here’s one more just for fun.
Let’s say you just completed setting trusses on a house. As you walk through the house admiring your work, you notice this truss:
Something just doesn’t look right. What is it that catches your attention?

Looks like I am not going to get any help from the others on this one.
It looks to me to be a bit light in the webbing for the distance of the span.
I also don't see any plates fasting things together.
Why is there a 2' over hang on one side and not the other?
Is the "grasshopper" learning anything?

"It looks to me to be a bit light in the webbing for the distance of the span."
Not really. It has a 2X6 top chord. It's fairly typical of what I might see around here.
"I also don't see any plates fasting things together."
OOPS. You're right, but that's not what I was after.
"Why is there a 2' over hang on one side and not the other?"
That's fairly common - Could be a lot of reasons. There could be a false gable or something on one side where overhang isn't required.
Who are you going to believe, me or your own eyes?
I'll take that 1/2 "at a boy". 11 1/2 more to go to wipe out that "aaa s--t".
Thanks Boss Hog for the education.

Looks like there is a "mid-truss" bearing wall that is not reflected in the truss design: ie no web, king post, etc directly above the bearing wall.
I'm making an assumption here - truss drawings that I have worked with do not show interior walls unless they are load bearing...

I was afraid this one was too easy.
The truss may or may not be fine in this case - It depends on the situation.
If you had shop drawings of the trusses, you could check to see if it was called out as a bearing wall.
If not, it's best to call the truss manufacturer and ask. I really didn't give enough info in this post and drawing for anyone to be able to tell.
It's entirely possible that this situation is perfectly O.K. And it's also possible that this is wrong.
But I'd say it definitely needs to be questioned.

Does that mean I get the milkbones? If so, forward them to Blue - he has been beggin' for some and he really is a good dog... :-)
Matt
Sorry - I never promised any milkbones.(-:
There is only one way to find out if a man is honest ask him. If he says "yes," you know he is crooked.
Why you cheap SOB!!!... I aughta come over there and... Actually I'll send Blue to slap you around a bit... :-)
Matt
Dirsh, he's so cheap with his milkbones.
Now this is another one of his "im not giving out any milkbones".
Their aint a single plate showing and we don't get any milkbones for pointing that out!
The idea that that would be a midspan bearing point is ridiculous. I'ts friggin 33' span for gawd's sake! They don't need no stinkin' bearing points on a 33' span!

It's not ridiculous at all.
Sometimes I pick up interior bearings to reduce loads on girders. Like if this truss ties into a girder on the front of a garage, it might mean the difference between a 2 ply vs. a 3 ply girder.
Keep in mind I never said this truss NEEDED an interior bearing. I just said it should be questioned, since the bearing wall wasn't under the joint.

the truss isn't supported over it's off-center bearing point
I've presumed you are showing the truss engineer's drawing of the truss in question.
Since the engineer has shown and located the intermediate bearing wall, it seems to me that the truss design should reflect that. It doesn't bring its webbing to the corrrect point over that intermediate bearing.
But, if you are not showing us the truss engineer's drawing, but a drawing of how a truss, designed for three-point bearing, lays on its as-built wall plates, then I would have to say that the intermediate wall is in the wrong place, or that the truss engineer screwed up as stated above.
Lack of an overhang on one side is what catches my attention.
No gusset plates?
