| Feb 8, 2018 at 14:49 | comment | added | Wasabi | @Farhad, a hinge allows a beam to have different rotations to each side of the hinge. Since the rotation isn't resisted around the hinge, no bending moment appears around it. That's why the bending moment at B is zero. That's all that's meant by "cannot transfer moment". | |

All the hinge does is mean that the moment at B is 0, not that there is no moment anywhere. | |
