Question
**Problem Statement:**

A ladder is leaning against a vertical wall, and both ends of the ladder are at the point of slipping. The coefficient of friction between the ladder and the horizontal surface is \( \mu_1 = 0.155 \) and the coefficient of friction between the ladder and the wall is \( \mu_2 = 0.153 \).

Determine the maximum angle \( \alpha \) with the vertical that the ladder can make without falling on the ground.

**Diagram Explanation:**

The diagram shows a ladder leaning against a wall, forming an angle \( \alpha \) with the vertical wall. The bottom of the ladder is in contact with a horizontal surface. Friction forces are indicated by \( \mu_1 \) at the base (horizontal surface) and \( \mu_2 \) at the wall (vertical surface), where these are the coefficients of friction preventing slipping.

**Answer:**

\( \alpha = 18.6^\circ \)

*This answer is marked as incorrect in the red box.*
