Assumptions
11
*Sheet is simply supported on all four edges
12
*Weight is concentrated at the center
13
*Maximum acceptable deflection is 5% of the width "b" or 3 inches, whichever is less
14
*The maximum allowable continuously imposed stress for a material is less than the tensile strength for the material because continuously imposed stress at levels higher than what is allowable can cause stress crazing and/or failure
