L Bar Structural Question

  1. Mar 27, 2016 #1
    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.

    Thanks for answering

    z.

    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.
