Rectangular plate; one edge fixed, opposite edge free, remaining edges simply supported loading 1/3 of plate from fixed edge.

 Rectangular plate; one edge fixed, opposite edge free, remaining edges simply supported. 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/m2, 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/m2, lbs/in2)
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
γ = Constant From Table A
