Hi Charles,

       Much less than that. You specified a curve of 1000 ft, presumably the 
radius. 
       If your strip is 6" long
       Center deflection = (0.25)^2 / 2000 x 12 inches = 0.000375"

       Regards,

Hi Charles,



       Much less than that. You specified a cu=
rve of 1000 ft, presumably the radius. 

       If your strip is 6" long

       Center deflection =3D (0.25)^2 / 2000 x=
 12 inches =3D 0.000375"
