Given: A cylindrical pressure vessel contains a gas at pressure of 30 psi. The radius, R, is 6.5 in., and the thickness, t, is 0.45 in. Req'd: |
|
|
Solution: The hoop and longitudinal stresses are given by: sH = pR/t = (30 psi)(6.5")/0.45" = 0.433 ksi sL = pR/2t = (30 psi)(6.5")/2(0.45") = 0.217 ksi Using the stress transformation equations or the Stress Transformation Calculator, the maximum in-plaane shear stress is:
Since the shear stress in the hoop-longitudinal frame is zero, we get:
