Contact Stress Roller Contact Flat Plane

Contact stresses on roller in contact with Flat plate.

When a Roller is in contact with a flat plate, a line contact is obtained, giving a rectangular contact area of very small width. depending on the load and materials.

E = Young's modulus (psi)
F = load ( lbsf)
r = radii (in)
L = Length (in)
v = Poisson's ratio
