Bicone
Bicone
Two cones placed base-to-base.
The bicone with base radius r and half-height h has surface area and volume
S = 2pirsqrt(r^2+h^2)
(1)
V = 2/3pir^2h.
(2)
The centroid is at the origin, and the inertia tensor about the centroid is given by
![画像: I=[1/(20)M(2h^2+3r^2) 0 0; 0 1/(20)M(2h^2+3r^2) 0; 0 0 3/(10)Mr^2].](/index.cgi/contrast/https://mathworld.wolfram.com/images/equations/Bicone/NumberedEquation1.svg){kind=link}
