## Homework Statement

Hey guys I'm having trouble drawing the bending moment diagram for this beam with a hinge?

I'm not sure where to start? I've looked at stuff online and its completely different to the stuff in my textbook

## Homework Equations

equilibrium equations

ƩFx=0 ƩFy=0 ƩM=0

Am I right to say that Ay=0 because the moment at the hinge is 0?

ƩMb=0 so

4m*Ay=0 --> Ay=0?

## The Attempt at a Solution

I know you start with the equilibrium equations to find the reactions but I'm not sure that what I am doing is right?

Any help with drawing the BMD would be appreciated :)
