![### Problem Description
As shown below, on Venus, a beam of length \( L \) is leaning against a frictionless wall and is in static equilibrium. The center of mass of the beam is located \( 0.6L \) from the lower end of the beam, and the wall is exerting a force of 4 N on the beam.
### Diagram Explanation
In the diagram accompanying the problem:
- The beam is shown leaning against a vertical wall.
- It forms an angle of 79° with the horizontal floor.
- A red dot marks the center of mass, located 0.6 times the length of the beam from its lower end.
- There is an arrow indicating the direction of the 4 N force exerted by the wall on the beam.
### Objective
Determine the beam's mass and the minimum coefficient of static friction between the floor and the beam.
#### Variables to be Found
- **Beam's mass**: __________
- **Minimum coefficient of static friction (\( \mu_s, \text{ min} \))**: __________](https://content.bartleby.com/qna-images/question/cb02a115-6c25-4160-8b34-cae01e1dd2a2/b55bbccd-0935-45b2-877d-34c26cb4718d/cer3idp_thumbnail.jpeg)
