I'm working on a project to replace hollow structures, (pipe, sq. tube, ect...) with open structures, (channels, angle iron, ect...). It's been a while and I think that all I would have to do is compair the moment of inertia for each of these shapes and make sure that they match or are larger than that of the original shape.
example:
3" sch40 pipe, 3.5" OD, 3.068" ID
I=3.016
equivalent angle iron
4"x4"x1/4"
I=3.04
Sorry if this is a stupid question, it's been years since I've had to do anything like this.
Thanks
