Uniform loading
over 1/3 of plate from fixed edge. 
Stress Maximum at center of fixed edge:
and  R = γqb 
Symbols used:
q = Applied Load or Force to Flat Area of Plate (N/m^{2}, lbs/^{2})
v = Poisson’s ratio (assumed to be 0.2)
t = plate thickness, (m, in)
a = plate length, (m, in)
b = plate width, (m, in)
σ = stress, (N/m^{2}, lbs/in^{2})
R = Reaction force per unit length (N/m, lbs/in) normal to the plate surface exerted by the boundary support on the edge of the plate.
β = Constant From Table A
