In this paper a new inlet distance variable for the starved rolling traction is introduced. By applying a statistical linear regression analysis to the starved E.H.L. question, this new inlet distance parameter enables a seminumerical formula for the prediction of the starved isothermal and nonisothermal rolling traction to be derived. The formula applies for a starved E.H.L. line contact and covers a wide range of the nondimensional materials, thermal loading, speed, load and inlet distance variables. A numerical example using several of the equations developed in this paper has been included in Appendix 1. For the isothermal case, the general formula developed shows good agreement with the two specific semianalytical results reported by Archard and Baglin [11], 1975.
