I need help with this question attached, please

### Diagram Explanation In the figure, we have a system involving two blocks, labeled A and B, connected by a rope over a pulley. - **Block B:** - Mass: 20 kg - Positioned on a horizontal surface. - **Block A:** - Mass not specified in the image. - Hangs vertically, suspended by the rope. - **Rope and Pulley System:** - The rope runs over a pulley, changing direction by 90 degrees. - The section of the rope attached to Block B is horizontal, while the section attached to Block A is vertical. - The pulley redirects the rope at a 45° angle from the horizontal plane to attach to Block A. ### Understanding the Forces - **Forces on Block B:** - The weight of Block B acts downward, while the tension in the rope acts horizontally. - **Forces on Block A:** - The weight of Block A acts downward, and the tension in the rope acts upward at a 45° angle to the vertical. This setup could be used to study static equilibrium, mechanical advantage, or the effects of friction and various forces within the system.

### Problem Statement Block B in **Figure 1** rests on a surface for which the static and kinetic coefficients of friction are 0.75 and 0.40, respectively. The ropes are massless. ### Question - Part A **Objective:** Determine the maximum mass of block A for which the system remains in static equilibrium. **Instructions:** Express your answer with the appropriate units. **Input Box:** - \( m_A = \) [Value] [Units] - Submit Button - Request Answer Link **Additional Information:** - You can view available hint(s) by expanding the "View Available Hint(s)" section. ### Explanation The question involves evaluating the conditions for static equilibrium of a system consisting of block A and block B, with block B resting on a frictional surface. You are tasked with ensuring that the forces involved do not exceed the limits set by the static friction coefficient to determine the maximum allowable mass of block A while still maintaining equilibrium. Use the coefficients of static and kinetic friction provided to inform your calculations.
