Stress and Reaction Force
Reaction Force
Stress and Reaction Force at x = 0, z = 0.4b if a ≥ 0.375b, or Z = 0.2b if a < 0.375b
Reaction Force
Where used:
E = Modulus of Elasticity (lbs/in^{2})
q = Total load or force to Plate (lbs/in^{2})
v = Poisson’s ratio (assumed to be 0.3)
t = plate thickness, (in)
a = plate length, (in)
b = plate width, (in)
σ_{b} = stress, (lbs/in^{2})
R = Reaction Force (lbs/in)
