WebbIn the present paper three problems in the simplified theory of rolling contact are investigated. As to the first problem, three benchmark loadings, derived by kalker in 1973 for hertzian rolling contact, are in existence. Each of these loadings gives rise to a value of the flexibility parameter of the simplified theory.
