I did use exactly the same formulas as you gave now, but I found where I went wrong the other day: I calculated the separated integrals for R, and then presumed that the result for z° would we similar in form. So for this second calculation I forgot that R is not a variable. I did the...

As a retired chemist, it’s a very long time (40 years) that I haven’t done any integration calculus, so I forgot quite a lot of it. But I’ll try: Let’s consider a sphere (radius R, density ρ) from which a cap is cut with a height (= the “arrow”) h and a radius of the cut circle: r. Then I...

That's easy: half of that, of course. But further on ? Do you suggest that the Moment Of Inertia of the cap is then to be calculated from the half sphere volume and the relation between cap volume and half sphere volume ? AV

Hi, I'm trying to find the formula for the moment of inertia of a spherical cap relative to the axis perpendicular to its flat area. I know it should be done by (triple) integration, but it's a very long time since I've done that kind of math ! So, if someone out there knows the formula ...
