i m just using the calculator from my laptop,and i was getting that result,thank you for your help if there is anything i can help you,just tell me
What pressure would a strain of 40 µε indicate?

SUMMARY
The discussion centers on calculating the maximum allowable pressure for a cylindrical pressure vessel with a 2m diameter and 4m length, using a factor of safety of 4. The Young's Modulus is 290 GN/m² and the Yield Stress is 500 MPa. The maximum allowable pressure, calculated using the hoop stress formula, is determined to be 0.75 MPa after dividing the calculated hoop stress of 3 MPa by the safety factor. Additionally, the pressure corresponding to a strain of 40 µε requires the application of Hooke's Law in three dimensions, considering the relationship between hoop and axial stresses.
