Calculate the internal shear (V), axial (N), and bending moment (M) in the beam at its mid-length.

Now heres what av figured out so far. Since its a fixed support at both ends there will be a vertical (V) and horizontal (V) reaction and also a bending moment (M). I got stuck from that point as when you take the moment about one point of the beam you have two unknowns (the Ms). Unless, since the beam is symmetrical, the vertical reactions are distributed equally between the two points? But still you would have the two unknown Ms. Any advice?

The distance (in mm) that the left hand end of the beam moves down under the given loading.

Dont understand how to do this question at all anyone able to help?

Cheers for the help
