**Topic: Calculating Force on a Semi-circle Side Wall**
#### Instructions
1. **Objective**: Calculate the resultant force \( F_R \) on the semicircle side wall.
2. **Task**: Label the x and y coordinates of the center of pressure.
#### Diagram Explanation
- **Left Diagram**:
- A horizontal semicircular shape is depicted with a straight horizontal line above it, labeled with \( \gamma_w \) (representing the specific weight of water).
- **Right Diagram**:
- Shows a side view of a semicircular area.
- The diameter of the semicircle is labeled as 10 feet.
- The height from the top edge to the center of the semicircle is given as 3 feet, indicating the depth of water above the center.
#### Steps for Calculation
1. **Calculate the Hydrostatic Force**: Use the formula for hydrostatic force on a submerged vertical surface to find \( F_R \):
\[
F_R = \gamma_w \cdot A \cdot h_c
\]
Where:
- \( A \) is the area of the semicircle.
- \( h_c \) is the depth to the center of pressure.
2. **Determine the Center of Pressure**:
- Calculate the coordinates by considering the distribution of pressure over the shape.
For detailed formulas and calculations, refer to fluid mechanics resources specific to hydrostatic forces on curved surfaces. These concepts apply fundamental principles of physics and engineering to solve practical problems related to buoyancy and pressure distribution.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4ce8b870-93ef-497a-8c2a-bbbd1041dd5b%2F017c1b24-82f2-4107-854b-094bfcf02adf%2Fp49jiy_processed.jpeg&w=3840&q=75)
