Consider regular polygons with number of sides n = 3, 4, 5 ....... as shown in the figure. The centre of mass of all the polygons is at height h from the ground. They roll on a horizontal surface about the leading vertex without slipping and sliding asdepicted. The maximum increase in height of the locus of the centre of mass for each polygon is Δ . Then Δ depends on n and h as :
