Moments of inertia for flat figures – example calculation
The moments of inertia of flat figures (cross-sections) are key parameters in structural strength analysis, particularly when analyzing the bending of beams. In this article, we will focus on practical examples of calculating moments of inertia for various types of...
Internal forces in beams – calculation example
Let's return to the topic of "Internal forces in a beam". Understanding the distribution of internal forces in a beam is essential for assessing its strength. In this article, I will present an example calculation of internal forces, such as axial, shear, and bending...
Gerber Beam (with hinges) – calculation example
In the previous article, I presented the procedure for calculating support reactions in the case of straight (continuous) beams. If you haven’t read it yet, I encourage you to catch up on the material, and then proceed with calculating beams online using the EquiBeam...
Beam Calculation – Example
After reviewing the theory on calculating support reactions, it’s time for some practice. In this article, I will analyze two typical examples to help you better understand how to “calculate beams” in practice – i.e., perform static and kinematic analysis and...
