Linear Momentum Balance

This lecture covers the concise local statement of linear momentum balance, continuity, and the re-casting of linear momentum balance. It delves into the analysis of the linear momentum of a con-shaped material, emphasizing the importance of continuity in the balance equations. The instructor discusses the derivation of continuity from mass conservation and the implications for analyzing particle motion. The lecture also explores the use of a specific form to analyze the linear momentum balance and the significance of considering continuity in the process. Furthermore, it addresses the evaluation of divergence and the application of the divergence theorem in understanding the linear momentum balance of con-shaped materials.
