Fluid Kinematics - VI: Fluid Deformation and Stress Tensor

Explore the fundamental concept of the stress tensor in this 52-minute lecture, a critical tool for analyzing internal forces within a continuum. Begin by examining the nature of surface and body forces and their relationship to normal vectors and differential areas. Delve into the detailed formulation of stress components, including both normal and shear stresses. Conclude by discussing the conditions under which the stress tensor exhibits symmetry, emphasizing its physical and mathematical significance in fluid mechanics analysis.
