Energy methods

Definition

Energy methods are analytical techniques used to evaluate the energy interactions within a mechanical system, focusing on energy conservation principles. These methods are crucial for understanding how energy is transferred, transformed, and conserved, particularly in the analysis of forces and movements in systems like tethers in airborne wind energy systems. By applying these principles, one can assess the structural integrity and performance of tethers under various load conditions.
