This calculator computes the displacement of an annulus plate, clamped on the inner edge, under a ring load.

Inputs
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

w_max = w(r = r_o) = 0.207125815105 mm 0.207 mm

The maximum bending moment occurs at the fixed edge of the plate, r = r_i.

The maximum stress occurs at the fixed edge of the plate near surface, r = r_i, z = ±h/2.
