Flat Rectangular plate, Three Edges Fixed, One Edge Loading Uniform over 2/3 of Plate from Fixed Edge.

 Rectangular plate; Three Edges Fixed One Edge Free Loading Uniform over 2/3 of Plate from Fixed Edge At x = 0, z = 0
Stress and Reaction Force Reaction Force Stress and Reaction Force at x = ± a/2, z = 0.6b for a > b of z = 0.4b for a ≤ b 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
