Loading:
 Ring Loading Pr = N/m dyne/cm dyne/mm Kgf/m gf/cm gf/mm lbf/ft lbf/in Loading Radius rL = km m cm mm micron mi yd ft in mil
Geometry:
 Outer Radius ro = km m cm mm micron mi yd ft in mil Inner Radius ri = Thickness h = km m cm mm micron mi yd ft in mil
Material
 Young's modulus E = Pa kPa MPa GPa psi ksi lbf/ft^2 kgf/cm^2 atm bar mmHg inHg ftH2O Poisson's ratio =
Output:
 Unit of displacement w = km m cm mm micron mi yd ft in mil Unit of stress = Pa kPa MPa GPa psi ksi lbf/ft^2 kgf/cm^2 atm bar mmHg inHg ftH2O

 Displacement  wmax = w(r = ro) = 0.207125815105 mm 0.207 mm
 Stress The maximum bending moment occurs at the fixed edge of the plate, r = ri. The maximum stress occurs at the fixed edge of the plate near surface, r = ri, z = ±h/2.  max = 2.25 MPa 2.25 MPa
