Transcribed Image Text:### Diagrams: Mechanical Equilibrium Concept
**Description:**
In the illustration above, we see a person standing on a plank supported by two supports labeled "Support 1" and "Support 2."
- The plank is 5.0 meters long, with distances marked on it.
- The left side or "Support 1" is shown supporting the plank at a distance of 2.0 meters from the edge where the person is standing.
- The right side or "Support 2" supports the plank at a distance of 3.0 meters from the left support.
- The plank is colored light brown and the supports are represented as triangular structures in grey.
This diagram is often used to explain concepts of static equilibrium and the distribution of forces. It can illustrate how the weight of the person and plank are shared by the two supports depending on the position of the person on the plank. Understanding these principles can be fundamental in fields such as engineering, architecture, and physics.
