5- Verify that the change in radius of a thin-walled spherical pressure vessel when subjected to internal pressure p is Ar= where E is Young's modulus, is Poisson's ratio, r is the sphere radius, and t is the wall thickness. 14.11mm Pr 2Et (1-1) 14.15mm 85MPa 6-A 10mm by 10mm square is etched onto a metal bar prior to loading. Upon loading, the dimensions of the etched shape become those indicated on the figure. Determine Young's modulus E and Poisson's ratio of the bar material. 5- Verify that the change in radius of a thin-walled spherical pressure vessel when subjected to internal pressure p is Ar= where E is Young's modulus, is Poisson's ratio, r is the sphere radius, and t is the wall thickness. 14.11mm Pr 2Et (1-1) 14.15mm 85MPa 6-A 10mm by 10mm square is etched onto a metal bar prior to loading.
