The following summary shows the results obtained for values of 
t d 2 y 
at the ends of the diameters of rectangular and square plates, 
with a comparison of the values obtained from Grashof’s approximate 
formulae. It is to be noted that these are the only points to which 
Grashof’s formulae apply.
