Contact Stress Sphere in Contact Flat Surface Equation

The following equation will determine the contact stress between a sphere and a flat surface with known young's modulus and applied load.

Where:
E = Young’s modulus
F = load
r₁, r₂ =radii
v = Poisson’s ratio

Contact stresses two sphere's in contact same material and differnet spherical radius.
