How many lies could Pinocchio tell before it became lethal?

Steffan Llewellyn


This paper investigates how many lies Pinocchio could continuously tell before it would become fatal, treating the head and neck forces as a basic lever system with the exponential growth of the nose.  This paper concludes that Pinocchio could only sustain 13 lies in a row before the maximum upward force his neck could exert cannot sustain his head and nose. The head’s overall centre of mass shifts over 85 metres after 13 lies, and the overall length of the nose is 208 metres.
