A solid shaft with D = 100 mm is loaded with an axial force P = 200 kN and a torsional force kNm. For point A, see Figure 4, which is located on the surface of the shaft: a) What are the coordinate voltages? b) Draw the stress distribution (above the cross section - yz-plane) for elastic state, partial plastic state and complete plastic state. c) What is the cross-sectional module for plastic condition.
