1. The cantilever bent pipe shown is fixed at C. Determine the internal loadings at a section 8 in from C and calculate the state of stress at A. Show the state of stress on 2D and 3D elements.

2. The solid shaft has a radius of 0.5 in. and is made of steel. Determine the internal loading at the centroid of the cross-section to determine the state of stress at A located on the outer surface. Show the state of stress on 2D and 3D elements. Determine the principal stresses, maximum shear stress, and the planes on which they act.
