The results show that the fracture was caused by the banded structure which decreased the permitted rotational moment and resulted in the torsional fracture of the bolts during installation process.

Upgrading it to give the exact latitude and longitude of the collision wasn’t simple work, since Chesley had to factor in the spin, orientation and rotational wobble of the Earth at each moment.

If I know the moment of inertia, then I know how much rotational kinetic energy there is.
