Require assistnce as new to the efund concept. I'm working on a project that I wish ti know which formula in efund will yield the load-bearing capacity of an S beam and a W beam. However the S one is made up of two smaler ones weilded together.
It's made up of 2 S5 with a flnge of .5"X8.5"pllus the top with 1/4 X 5 X 5/8 inch.
The W is 10 " X 10" with the flange 3/8" and the rest 1/2". Its a very important project.
I've tried to get the go of the formulas but haven't succed or I'm not all that confident with what I've calculated.
Thank you for your time and assistnce
