80mm Acrylic Sheet Stiffness: Bc = 1/12 * Eh³ = 1/12 * 3359.7 * 80³ = 143347200N-mmm
100mm Acrylic Sheet Stiffness: Bc = 1/12 * Eh³ = 1/12 * 3359.7 * 100³ = 279975000N-mmm
150mm Acrylic Sheet Stiffness: Bc = 1/12 * Eh³ = 1/12 * 3359.7 * 150³ = 944915625N-mmm

80mm Acrylic Sheet Deflection: f = Table Coefficient × ql4 / Bc 
= 0.01013 × 0.012 × 10504/143347200 = 1.03mm 

100mm Acrylic Sheet Deflection: f = Table Coefficient× ql4 / Bc 
= 0.01013 × 0.012 × 10504/279975000 = 0.53mm 

150mm Acrylic Sheet Deflection: f = Table Coefficient × ql4 / Bc 
= 0.01013 × 0.012 × 10504/944915625 = 0.16mm 
Acrylic sheet deflection calculation does not consider the sheet weight or any load applied of the sheet itself.
