Question
**Problem 4** Determine the maximum and the minimum values of weight \( W \) which may be applied without causing the 25-kg block to slip. The coefficient of static friction between the block and the plane is \( \mu_s = 0.2 \), and between the rope and the drum \( D \) is \( \mu'_s = 0.3 \). **Diagram Explanation:** The diagram shows a setup involving a 25-kg block resting on an inclined plane with an angle of 45 degrees. The block is connected via a rope to a drum labeled \( D \). Another weight, labeled \( W \), hangs from the drum. The configuration illustrates a system where frictional forces act between the block and the inclined plane, and between the rope and the drum, influencing the block’s tendency to slip down the plane.
