Acrylic panel stringths

[wellyz]

Hi just wondering if anyone knows if there is a strength  calculator or Programe for acrylic sheet like the glass one.

Say for a panel 3500 x 750 in a fiber glass tank that measures 3600x1000x800

Any help would be greatly appreciated. 

Thanks Llewellyn

for that size i would go 20mm thick as i got deflection of about 20mm 0n a 10mm thick sheet at 800mm between supports
