theoretically, bending moment should ends at bending moment = 0 , am i right ?
The Attempt at a Solution
Here's my sketch of SFD and BMD ,my bending moment doesnt return to 0 , which part of my working is wrong ... to find bending moment (M) , i get M =Vdx , where V =shear force
Vdx = area of the shear force diagram
for the BMD , I let downwrads as positive ....
