11.4 (A/B). Compare the strain energies of two bars of the same material and length and carrying the same gradually applicd compressive load if one is 25 mm diameter throughout and the other is turned down to 20 mm diameter over half its length, the remainder being 25 mm diameter. If both bars are subjected to pure torsion only, compare the torsional strain energies stored if the shear stress in both bars is limited to 75 MN/m². [0.78, 222]

A sample of silicone breast implant, polydimethylsiloxane (PDMS), is placed under unconfined compression. The magnitudes of the resulting longitudinal and transverse strains have been measured to be 2.7 and 1.341, respectively. The young's modulus of the implant is 500 kPa. Calculate the shear and bulk moduli.
Sketch two more stress-strain diagrams, again one for a ductile material and one for a brittle material. Draw the stress-strain diagrams so that the modulus of toughness for the brittle material is greater than the modulus of toughness for the ductile material.
