Abstrakt

The paper treats the following question: How does a piece of sugar, considered as a rectangular prism, split if one tries to break it by gripping it at two opposite corners? Zermelo first analyzes the physical conditions and then provides a mathematically simple solution together with generalizations resulting from replacing the cross-section rectangle by ellipses and parallelograms.
