Lecture
This lecture covers the derivation of linear momentum balance equations from mass conservation, focusing on the continuity and re-casting of the balance. It analyzes the linear momentum of a con-shaped particle and explores the consequences of the balance equations. The lecture also delves into the divergence theorem and its application in evaluating divergence, emphasizing the conservation of angular momentum. The instructor discusses the surface and volume integrals, as well as the significance of continuity in the linear momentum balance.
