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?
Click For Summary
The discussion revolves around calculating the maximum allowable pressure for a cylindrical pressure vessel and determining the pressure corresponding to a strain of 40 µε. The maximum allowable pressure, considering a safety factor of 4, is derived to be 0.75 MPa based on a calculated hoop stress of 3 MPa. Participants discuss the application of Young's modulus and the hoop stress equation, emphasizing the need for proper understanding of yield criteria, particularly the von Mises criterion. For the strain calculation, the correct approach involves using the relationship between stress and strain, but participants express confusion over the necessary parameters, such as Poisson's ratio. The conversation highlights the challenges faced by distance learning students in grasping complex engineering concepts.
