aluminum treadplate

[AUtigr]

Hello,

I need to know the moment of inertia perpendicular the the face of an aluminum plate that is 1/8" thick and 48" wide.

I can't find any info anywhere.

thanks

For a rectangular section, the moment of inertia is (1/12)*b*h^3, where b is the plate dimension parallel to, and h is the dimension perpendicular to, the axis about which the moment of inertia is being calculated.

I am not clear from your message as to about which axis you are calculculating the moment of inertia.

I hope this helps.
