Assumptions
11
*Sheet is simply supported on all four edges
12
*Weight is uniformly distributed over entire sheet
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

3Specify the material you would like to use
20
4Enter the weight you would like to support in pounds
21
5Maximum acceptable deflection will be displayed
22
6Acceptable design factors will be highlighted in blue
23
7Deflections meeting acceptable limit will be highlighted in blue
24
8Acceptable standard thicknesses will have BOTH deflection and design factor highlighted in blue
