These are the kinds of problems which are analyzed by applying Newton's Laws of motion to the toppling structure; i.e., that's why you took a dynamics class in college.
As with any problem involving statics or dynamics, start with a freebody diagram and determine what forces and moments are acting on the structure when it is at an arbitrary angle. It's not clear from you diagram how the process of toppling gets started.

Hi. The body is started by applying a horizontal force at the top until the body's centre of gravity causes it to topple, from this point gravity takes over.
My colleague in the office worked on it and made a spreadsheet. We would just like to confirm whether our thinking is correct. The spreadsheet is attached. It uses the energy approach in the first tab and the equations of motion in the second. Regards DerryckFalling Tower Forces.xlsx
