A two-state model is studied from a molecular dynamics description of a molecular system under shear. This model captures the main features of the response of a confined system under shear. It also generalizes the Tomlinson model for the response of a driven system. The two-state model agrees well with the direct numerical solution and offers a practical approach to investigate the response of sheared systems.
