Deformable Structures I

This lecture covers statically determinate and indeterminate systems, linear superposition, axial loading, axial stiffness, and the introduction of displacement fields and strain relations for deformable structures. The instructor explains the concepts using examples of simple trusses and generalized deformable solid bodies, emphasizing the application of Hooke's Law and the compatibility of displacement fields. The lecture also delves into the analysis of stress, strain, and axial stiffness in deformable structures, highlighting the importance of equilibrium and compatibility in determining internal loads and member elongations.
