This study discusses the effect of longitudinal roughness on the performance of a hydromagnetic squeeze film in conducting triangular plates. A stochastic random variable characterizes the longitudinal roughness of the bearing surface. The associated Reynolds’ equation is recourse to the stochastically averaging method of Christensen–Tonder, solving the Reynolds’ equation with Reynolds’ boundary conditions; the pressure is obtained which gives load profile as well. Unlike the transverse roughness case, here, it is found that the load bearing capacity increases due to the standard deviation related to roughness. This situation further improves with the involvement of negatively skewed roughness and variance (−ve). The effect of magnetization and conductivity elevates the situation further.
