Shear force and bending moment diagram for beam with concentrated moment

[Mattheo]

Homework Statement

This is the question that I am struggling with.

I need to plot shear force and bending moment diagram of it.

Homework Equations

The beam is in static equilibrium so algebraic sum of forces in x and y direction equal zero.
Also, moment is zero at any point.

The Attempt at a Solution

I didn't understand how I am going to deal with 50 kN m.

In the moment diagram at that point it is just a jump of 50kN m, nothing more
