Hoops stress and longitudinal stress in a boiler shell under internal ...
's modulus of the material is 200 GPa.
To find the radial stress, we can use the formula:
Radial stress = (Hoops stress - Longitudinal stress) / 2
Radial stress = (100 MN/m2 - 50 MN/m2) / 2 = 25 MN/m2
Now, let's calculate the strain using Hooke's law:
Strain = Radial stress / Young's modulus
Strain = 25 MN/m2 / (200 GPa * 10^6 N/m2) = 0.000125
Therefore, the strain in the boiler shell under internal pressure is 0.000125.
