For the circular bar, determine, Part 1. Determine the required diameter of the shaft for the given and Part 2. Taking the value of diameter given in the Data list,

a) Calculate the stress components and show the state of stress on cubic element taken from point A.

b) Determine the principle stresses at points A by using Mohrs circle. Calculate the oriantation of the principle stresses and show the results on a cubic elements.

c) Determine the max in-plane shear stress and associated average normal stress and the oriantation show the results on a cubic element, by using Mohrs circle.

Note: Solution should include the parts internal loadings, section properties, stress components
