Determine maximum bending stresses

Constructing the shear diagram

Considering the segment
from x = 1 m to x = 1.5 m

     area under
               load =   0.00 kN
     concentrated
             forces = 0.00 kN
     total shear
              force = 0.00 kN

        at x = 1 m,    V =   -10.00 kN
           total shear
                  force   =      0.00 kN
      at x = 1.5 m,    V =   -10.00 kN
