Two forces P$1=5$ kips and P$2=3$ kips are applied at directions perpendicular to the longitudinal z axis of a W$1240$ beam $($check table in Bb of sections standardized steel$),$ as shown in the beam. Determine at point b: The initial state of efforts. The corresponding Mohr circle, with the initial state located. The main state of correctly oriented effort and located in Mohr's circle. The maximum cutting state correctly oriented and located in Mohr's circle.
