Balloons!!: A demonstration of thin-walled pressure vessels

 

 Overview This is a simple demonstration of the basic principals underlying the behavior of thin-walled pressure vessels (TWPVs).  A balloon or balloons are used to show that hoop stresses are twice as high as longitudinal stresses in cylindrical pressure vessels. Principle The basic derivation for TWPV behavior states that for a cylindrical pressure vessel   […]
