An infinite elastic beam moves at constant speed across a frictionless rigid step. Steady-state solutions are obtained in closed form using both Euler-Bernoulli and Timoshenko beam models. With step height and speed as parameters, the noncontact regions, mode shapes, and foundation reactions are determined. The results show interesting qualitative as well as quantitative differences between the behavior of the Euler-Bernoulli and Timoshenko beams.
