Uneven I beam centroid
Uneven I beam centroid
(OP)
How do I find the centroid of an uneven I Beam at one end the flange is ten times bigger thatn the other....I looked at Efunda but keep getting a negative answer for it....I did the cumulative method of sectioned into smaller areas and I get answer that sounds better but its off a bit...
something is telling me its off.

2) your calc 16.99 looks good to me
3) i think your efunda calc is off 'cause the thickness cells havn't been divided by ten

Your spreadsheet would give the right answer if you just entered the actual dimensions, rather than dividing random numbers by 10.
