Question

The moment of inertia of a uniform solid regular tetrahedron of mass m and edge a about its symmetric axis is

Answer 1

The moment of inertia of a uniform solid regular tetrahedron of mass m and edge a about its symmetric axis is;

I = m* a²/20

I = moment of inertia of uniform solid regular tetrahedron

m = mass of uniform solid regular tetrahedron

a = sides of uniform solid regular tetrahedron
