Question

Calculate the increase in volume of a boiler shell 3 m long and 1.5 m diameter, when subjected to

an internal pressure of 2 N/mm2

. The thickness is such that the maximum tensile stress is not to

exceed 30 N/mm2

. E = 2.1 x 105 N/mm2

and 1/m = 0.28, Also calculate the change in diameter and

length.​
