A copper bar of 200 mm long with sections 50 × 50 mm is subjected to stresses of +20 N/mm^2 along the axis,

Question 1

A copper bar of 200 mm long with sections 50 × 50 mm is subjected to stresses of +20 N/mm2 along the axis, and −40 and +40 N/mm2 along sides. The increase in volume was observed to be 183 mm3. Determine the value of Poisson’* ratio, modulus of rigidity and bulk modulus, if E = 105 GPa.

Question 2

Principal stresses are +120, −40 and −40 N/mm2

Volumetric strain,
