Solution

The correct option is A 10


Considering equilibrium

VA+VB=3×6+12+6=36kN ... (i)



12×1.5+6×4+3×6×626×VB=0

VB=16kN

Taking | shear as +ve"

And slope of BMD = Ordinate of SFD at the section.

Slope of BMD just right to 'D' =16+3×2=10kN i.e., the slope of BMD is 10kN measured in clockwise direction with horizontal.
