The attempt at a solution
the question have a possible solution? that equation is based on stress is constant, so how to use this equation to proof? i m a year 2 student. i can only solve part i

I've been puzzling over this since you first posted the question . Part 2 does not make much sense as written .

It might make more sense if the wording ' Determine the stress at the top of H ' was changed to ' Determine the radius r at the the top of H ' and if you had actual values for the compressive strength and density of the concrete .

Finding the radius r would not actually be too difficult but our efforts might be wasted if our understanding of the question is wrong .

Sorry I can't be more helpful .
