Flat Rectangular plate, Three Edges Fixed, One Edge Uniform Loading over 1/3 of Plate

 Rectangular plate; Three Edges Fixed Uniform Loading over 1/3 of plate from fixed edge At x = 0, z = 0
Stress Reaction Force Stress at x = 0, z = 0.2b and At x = 0, z = b
Reaction Force At x = ± a/2, z = 0.2b
Stress Reaction Force Where used:
E = Modulus of Elasticity (lbs/in2)
q = Total load or force to Plate (lbs/in2)
v = Poisson’s ratio (assumed to be 0.3)
t = plate thickness, (in)
a = plate length, (in)
b = plate width, (in)
σb = stress, (lbs/in2)
R = Reaction Force (lbs/in)
β1,2,3,4 = Constant From Table A
γ1,2,3 = Constant From Table A
