We have a beam with 1 internal hinge just like the picture. we We know the internal hinge can not transfer moments between AB and BD. we We know the 30 kN force makes some moments on BD & AB!! if. If B (internal hinge) can not transfer moments between the two elements, then why does the 30 kN kN (which is applied on BD) makescause moments forin AB? i
I don't know if i'm clear enough but the 30 kN kN force makes some moments on AB while we know that no moments can transfer between AB & BD.
