Abbas AbdulMajeed Allawi

because the structure is free to move and not restraint.

Nazar K Ali Oukaili

Thank you Dr. Abbas

But there are stresses in different fiber locations across the section while the resultant not changes !!!!!

I mean there are balanced internal stress, but the resultant not change,

Exactly
