Hello I just joined this forum and this is my first thread here. This is my assignment question. I'm supposed to find elastic positive bending capacities around the horizontal axes for the following cross section shown in pic. The elastic stress in tension is 10 ksi and in compression is 15 ksi. First i calculated "I" that is second moment of inertia, then i substituted in Moment = (I) x(stress) divided by c. I also have problem finding in c, because vertical length is not same. I posted my attempt as well.
