ABSTRACT 

The Lagrange method is a method used to solve complex mechanical problems by utilizing kinetic and potential energy. This research examines the application of the Lagrange method to rigid body systems, where the position and orientation of the body are determined by general coordinates. This article uses a literature study approach from various relevant sources. The research results show that the Lagrange method is effective in solving mechanical problems in rigid body systems that cannot be solved using Newton's method.

Keywords: Lagrange method, Mechanics of rigid bodies, Generalized coordinates, Effectiveness of Lagrange method
