This calculator computes the displacement of a free circular plate under a uniformly distributed load with a simply-supported ring at r=r₀.

Inputs
Loading:	Uniform load p =   Pa kPa MPa GPa psi ksi lbf/ft^2 kgf/cm^2 atm bar mmHg inHg ftH2O
Geometry:	Support radius r0 =     km m cm mm micron mi yd ft in mil  Outer radius r1 =      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

w_max = w(r = r₁) = -0.467035862828 mm -0.467 mm

Note: Negative sign means the direction of maximum displacement is opposite to the direction of the loading.
