llustrates a cross-section of an aircraft fuselage. The floor beam of the aircraft is supported by the fuselage at its both ends. The floor beam has an ?-shaped cross-section and is subjected to 1.2 kN/m uniformly distributed load at its center. It is assumed that the fuselage only exerts vertical reactions on the ends of the beam andEI is constant.

Construct a free body diagram (FBD) of the floor beam, with all necessary labels.
