Hydrostatic force acting on beam

[Whatamiat]

Attached is the problem i am trying to get to grips with along with my current line of understanding,

The column seen is a side section slice from the design of a water tank.

The column is designed to take the load of the water.

The column is designed with 2 unequal angle 75x50x6 steel sections.

These sections are bolted together using m10 bolts at the distances shown in the attachment.

I am trying to find the forces acting on the bolts in order to confirm a m10 bolt is stong enough.

Is my line of thought right here?
Or am I missing something alltogether?

The water doesn't impose any significant load on the bolts. Both angles want to move together the same amount and the bolts don't do anything to prevent that movement.

Depends on what your bolts are bolted up to.

The other thing you can do is look at the stresses in the beam. Find your maximum shear and bending stress, which is at the fixed end.
