Hi, I have been reading about the cavendish experiment and in one equation they say that(adsbygoogle = window.adsbygoogle || []).push({});

[tex] T = 2 \pi \sqrt{\frac I k} [/tex]

where I is the moment of inertia and k is the elastic constant.

in my physics books i only find [tex] T = 2 \pi \sqrt{\frac m k} [/tex]

where m is the mass, not the moment of inertia, anyone know how they got to this equation?
