What is an indeterminate structure and how it could be analyzed? This lecture discusses this concepts and explains how the compatibility of deformation could be used for analyzing (determining internal forces) of a system of axially loaded eleements.
The main learning outcomes are:
Distinguish between determinate and indeterminate structures
Identify the degree of indeterminacy in structures
Apply compatibility of deformation to analyze indeterminate axial elements
