Flat Rectangular plate, Two Edges Fixed, Two Edges Free Uniform Loading over Plate from z = 0 to z = (2/3) b.

 Rectangular plate; Two Edges Fixed Two Edges Free Uniform Loading over plate from z = 0 to z = (2/3) b At x = 0, z = 0
Stress and Reaction Force Reaction Force Stress and Reaction Force at x = 0, z = 0.6b if a > b/2 or z = 0.4b if a ≤ b/2 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 = Constant From Table A
