The clamping of the friction disk is caused by the outwardly rolling of the steel ball along the slop rolling track under eccentric force.

In their paper, the co-authors argue that gravitational tidal heating caused by the gravitational friction of an earth-like exo-moon on an eccentric orbit around a Jupiter-like planet lying at a Jupiter-like distance from its parent star, could, in fact, create habitable conditions.
