**Problem Statement:** 2. Compute the horizontal force \( P \) required to prevent the block from sliding down the plane for the 100 lb block shown. Assume the coefficient of static friction to be 0.65. **Diagram Explanation:** The diagram shows a block on an inclined plane. Key components include: - The block is labeled with a weight \( W = 100 \) lb. - There is an arrow indicating a horizontal force \( P \) acting on the block. - The inclined plane forms an angle of \( 30^\circ \) with the horizontal surface. - The friction force counteracts the gravitational component along the plane to keep the block from sliding down. The problem involves calculating the magnitude of force \( P \) needed to ensure the block remains stationary on the incline without sliding.
