Static Determinacy II

Description

This lecture covers the concept of statical determinacy in 2D and 3D structures, discussing the necessary and insufficient number of supports and joints, examples of statically indeterminate systems, and the limitations of equilibrium conditions. It also explores the distinction between isostatic and non-isostatic systems, emphasizing the importance of constraints in ensuring static equilibrium. The lecture delves into hyperstatic systems, which require more constraints to maintain equilibrium, and hypostatic systems, which have insufficient constraints. Additionally, it explains the concept of instantaneous center of rotation (ICR) and its significance in analyzing rigid body motion.
