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. This is often demonstrated by twisting a piece of blackboard chalk between one's fingers. See more In the field of solid mechanics, torsion is the twisting of an object due to an applied torque. Torsion is expressed in either the pascal (Pa), an SI unit for newtons per square metre, or in pounds per square inch (psi) while torque is … See more Calculation of the steam turbine shaft radius for a turboset: Assumptions: • Power carried by the shaft is 1000 MW; this is typical for a … See more • List of area moments of inertia • Saint-Venant's theorem • Second moment of area See more The shear stress at a point within a shaft is: $${\displaystyle \tau _{\varphi _{z}}={Tr \over J_{\text{T}}}}$$ Note that the … See more The shear stress in the shaft may be resolved into principal stresses via Mohr's circle. If the shaft is loaded only in torsion, then one of the principal stresses will be in tension and the other in compression.
