Contact Stress Two Sphere's in Contact Equation Equations

The following equation will determine the contact stress between two balls or spheres of known radius, young's modulus and applied load.

E1, E2, = Young’s modulus
F = load
r1, r2 =radii
v1, v2 = Poisson’s ratio

Contact stresses two sphere's in contact different young's modulus and spherical radius.
