The crack e-f shafts and other mechanisms is often met, but the causes and unfolding way of the process are rarely entirely cleared up. The paper presents some theoretical appearances which are presented by technical bibliographical (part 1) and the experimental results which were obtained as a result of the test with the shaft of pump 125 P1A on its crack, plan ( part II ).
