Structural Systems with rigid bodies — Lesson 1

This lesson covers the concept of structural systems made out of rigid bodies. It delves into the classification of rigid bodies based on their dimensions and the ways they can be connected to form a system. The lesson further explains the concept of internal forces within a rigid body and how to analyze them. It introduces the terms axial force, shear force, and moment, and explains how these forces can be represented graphically. The lesson concludes with a discussion on different types of structural systems such as trusses, beams, frames, shafts, columns, and cables.

Key Takeaways

- Structural systems are made up of rigid bodies that are connected in various ways.
- Rigid bodies can be classified into one-dimensional, two-dimensional, and three-dimensional based on their dimensions.
- Internal forces within a rigid body, such as axial force, shear force, and moment, can be analyzed to understand the load a body can take.
- These internal forces can be represented graphically through axial force diagrams, shear force diagrams, and bending moment diagrams.
- Different types of structural systems include trusses, beams, frames, shafts, columns, and cables, each having unique characteristics and applications.
