A swimming pool has a slanted floor . There is no change in depth across the 4 meter width. Assume that water has a density of 1000 kg/m3.
If I have a 1 meter diameter circular viewing window at the middle of the pool floor, what would be the force required to hold it in place if a bolt is placed at its center of pressure? Where is the centre of pressure relative to the centroid? Be careful to indicate the origin of your y and x directions.
