Engineering Mechanics | Weight Density | Material Density | Force

This tutorial explains the term of force in mechanics and structural analysis.
How it is  described in physics and mathematics and how the force is derived from the material density. Check out this tutorial to learn more!

The derivation of the force is explained using a steel material as an example.
Finally, it becomes clear why the steel's weight density in both the programs and the standards for structural engineers is exactly 78.5 kilonewtons per cubic meter.

To understand it better, we select various materials in RFEM and look at their self-weight. The conversion from weight to a force for a specific cross-section will be shown in RFEM.

Finally, a self-weight in the form of a distributed load results from entering the material weight density and the section's cross-section area.
