I-Cremona: Structural Forces

This lecture introduces the i-Cremona applet, focusing on structural forces and subsystems. Students learn to use the applet to analyze forces, supports, and color-coded lines. They practice introducing gravitational forces and soil actions on columns, ensuring consistency in units. Definitions of forces, efforts, and subsystems are provided, along with guidance on using the glossary. The lecture emphasizes the importance of correctly inputting forces in the applet and understanding terms like stress, force, and deformation. Students are guided on activating the applet, troubleshooting common issues, and ensuring Java compatibility. The lecture concludes with a detailed overview of the main buttons and functionalities of the i-Cremona applet.
