An inverted T-shaped concrete beam (B₁) in the figure, with centroidal axis X-X is subjected to an effective prestressing force of 1000 kN acting at the bottom kern point of the beam cross-section. Also consider an identical concrete beam (B₂) with the same grade of concrete but without any prestressing force. The additional cracking moment (in kN.m) that can be carried by beam B₁ in comparison to beam B₂ is _______. (rounded off to the nearest integer).
