A layer of steel (E=208GPA) tape 3/2 mm thick is wounded on a copper (E = 110 GPa, v = 0.3) made thin-cylinder with 4 mm thickness and internal diameter 150 mm. Assuming the winding was done when cylinder has zero intemal pressure. What will be the tensile stress in the winding tape if the purpose was to ensure that the cylinder will be subjected to 3.5MPA internal pressure. Also, the hoop stress will be limited to 37 MPa

A layer of steel (E-208GPA) tape 3/2 mm thick is wounded on a copper (E = 110 GPa, v = 0.3) made
thin-cylinder with 4 mm thickness and internal diameter 150 mm. Assuming the winding was done
when cylinder has zero internal pressure. What will be the tensile stress in the winding tape if the
purpose was to ensure that the cylinder will be subjected to 3.5MPA internal pressure. Also, the hoop
stress will be limited to 37 MPa.
