고체역학 (Gere) — Applications of Plane Stress: Problem 8.2-10

8.2-10 Solve the preceding problem for the following data: diameter 1.0 m, thickness 48 mm, pressure 22 MPa, modulus 210 GPa, and Poisson’s ratio 0.29. (Reference Problem 8.2-9: A spherical tank of diameter 1.2 m and wall thickness 50 mm contains compressed air at a pressure of 17 MPa. The tank is constructed of two hemispheres joined by a welded seam. (a) What is the tensile load \(f\) (N per mm of length of weld) carried by the weld? (b) What is the maximum shear stress \(\tau_{max}\) in the wall of the tank? (c) What is the maximum normal strain \(\epsilon\) in the wall?)
