Unsure of the approach to solving the friction coefficients.
![### Problem Description:
Beam \( AB \) has a negligible mass and thickness, and supports the 200-kg uniform block as shown in **Figure 1**. It is pinned at \( A \) and rests on the top of a post, having a mass of 20 kg and negligible thickness.
### Task:
**Part A**
Determine the two coefficients of static friction at \( B \) and at \( C \) so that when the magnitude of the applied force is increased to 270 N, the post slips at both \( B \) and \( C \) simultaneously.
**Instructions:**
Express your answers using three significant figures separated by a comma.
Input box for response: \( \mu_B, \mu_C = \) [Text field]
**Feedback:**
Incorrect; Try Again; 2 attempts remaining
### Figure Explanation:
The diagram shows a beam \( AB \) with a length of 3.0 m, supported on one end at point \( A \) and resting on a post at point \( B \). The block is centrally located on the beam. An applied force denoted as \( P \) acts at an angle of \( 75^\circ \) and has a magnitude of 270 N. The beam rests on a support at \( C \), located 0.75 m from the edge of the beam at \( B \).
