Investigation of motion of rigid rod on a circular surface using modified homotopy perturbation method

A new approach of modified homotopy perturbation method (MHPM) is centered in current paper to showcapability of this method in solving a strong non-linear system in different initial conditions. The MHPM is awell-established method which can be easily extended to any nonlinear equation in other practical engineeringbranches like: electromagnetic and waves, fluid mechanics,civiland its structures an telecommunication.In this article the non-linear equations of motion for a rigid rod on the circular surface without slipping havebeen stated and then the governing equations have been solved via MHPM .
