Message to Edit: HTML is ON UBB Code is ON Smilies Legend	Originally posted by Robert Pearlman on 01-11-2017 01:58 PM Per Dennis Jenkins: <BLOCKQUOTE>[i]The cases will be empty. There have been various analyses performed, and the consensus is that propellant does not affect the bending characteristics of the cases since the flexible spot is the joints. The propellant does not cover the field joints so it doesn't matter if its there or not. Although the mass might be slightly beneficial in some scenarios, it also greatly complicates the design of the seismic isolator the stack sits on (much easier to design an isolator for a 500,000-pound object than for a 3,000,000-pound one). The mass of propellant, especially up high, would also tend to make the stack sway more.[/i]</BLOCKQUOTE>
