[PSUBS-MAILIST] Hull Calculator

[Jon Wallace <jonw@psubs.org>]

Sean, Cliff,

Using the hull calculator spreadsheet it appears that ribs can take on 
numerous dimensions to achieve similar results.  For example, with a .5 
inch hull I can get very similar numbers for the Pa of inter-stiffener, 
stiffener, and longitudinal calculations by using both .25 inch thick 
webs and .5 inch thick webs.  The thicker web requires a shorter length 
and flange to get the same (or very closely similar I should say) 
results as the .25 inch web.

Is there any specific reason or rule that the web thickness must match 
the hull thickness?  It appears that in this case the same end result in 
water depth can be achieved by using the lighter .25 inch web material.

Jon
