Deformable Structures I: Introduction

This lecture covers the computation of deformations in structures by combining struts and rigid members, starting with the stress and strain in straight bars. It explains the application of equilibrium in the undeformed configuration and the approximation of arcs of circles by their tangents. The instructor demonstrates the determination of forces in all members and the changes in lengths using displacement diagrams, providing a recipe for analyzing deformable isostatic structures. The lecture concludes with an example of a hyperstatic truss and outlines the process of solving statically indeterminate systems. The audience is encouraged to practice these concepts for a deeper understanding.
