Torsion mechanics Wikipedia

If the shaft is loaded only in torsion then one of the principal stresses will be in tension and the other in compression These stresses are oriented at a 45 degree helical angle around the shaft If the shaft is made of brittle material then the shaft will fail by a crack initiating at the surface and propagating through to the core of the shaft fracturing in a 45 degree angle helical shape
