A thin cylinder 150 mm internal diameter and 2.5 mm thick has its ends closed by rigid plates and is then filled with water. When an external axial pull of 37 kN is applied to the ends, the water pressure is observed to fall by 0.1 N/mm2. Determine the value of Poisson's ratio. Assume –
E = 140000 N/mm2
K = 2200 N/mm2
