Symbols used:
E = Modulus of Elasticity (N/m², lbs/²)
q = Applied Load or Force to Flat Area of Plate (N/m², lbs/²)
v = Poisson’s ratio (assumed to be 0.3)
t = plate thickness, (m, in)
a = plate length, (m, in)
b = plate width, (m, in)
σ _max = maximum stress, (N/m², lbs/in²)
y_max = Maximum deflection (m, in)
α = From Table A
β = From Table A
