EXERCISE PROBLEMS
1. Analyse the column shown in the Illustrative Example 1 when it is loaded by a triangular load of zero at inner radius (r = 0.2 m) to 0.4 GPa at the outer radius (r = 0.4 m).
2. Consider an assembly of two heavy circular shafts. The top shaft has inner radius of 0.5 m and outer radius of 0.75 m, while the bottom one has inner radius of 0.5 m and outer radius of 1.0 m. Shafts are restrained at the top and bottom surfaces to movement in the vertical direction. A uniform load of 1 GPa is acting as shown in Figure E1. Analyze the assembly employing 8-node isoparametric elements. Assume E = 20 GPa, v = 0.20 and restrain node 1 in the radial direction.
