Hi All.

Given a 20 inch L bar with 1" sides.

If 6 inches of this bar is buried in a concrete wall horizontally, which orientation would render the most downward force strength?

1. A V orientation with the tip of the V pointing down.

2. A V orientation with the tip of the V pointing up.

3. An 'L' orientation with one side horizontal and the other vertical.

My best guess is a V orientation with the tip of the V pointing down, but I'm not 100% sure of that.

My guess is the "L" position since vertical " l " part will be parallel to the load straight down...

Thank you. I also considered L position, but then only one side of the angle iron would be under tension on a load.......while the other would tend to just bend easily.

So was thinking the V position would put both sides under tension on a load........What do you think?

Anybody else?.........I guess it would take some kind of calculation to be sure though...but finding a formula for that might be difficult..

I do feel that the V position with the tip up would be the weakest.......since the sides would then be under compression and tend to bend easily......just a thought.
