Calculate torque for F4
![**Determining Torque on a Plywood Sheet**
The plywood sheet illustrated in the diagram measures 2.0 m × 2.0 m. Each of the four forces acting on the sheet has a magnitude of 8.0 N. The sheet is subjected to these forces relative to an axis perpendicular to the page, passing through the top left corner of the sheet.
**Objective:** Calculate the magnitude of the torque for each force.
### Diagram Review:
- **Center of Rotation:** This is located at the top left corner of the plywood sheet.
- **Grid Layout:** The sheet is divided into a grid by orange lines.
- **Forces:**
- \( F_1 \) (acting downward at the center of the bottom edge)
- \( F_2 \) (acting leftward at the center of the right edge)
- \( F_3 \) (acting rightward at the center of the sheet)
- \( F_4 \) (acting upward at the center of the top edge)
To determine the torque (\( \tau \)) generated by each force, we utilize the equation:
\[ \tau = F \cdot r \cdot \sin(\theta) \]
Where:
- \( F \) is the magnitude of the force,
- \( r \) is the perpendicular distance from the axis of rotation to the line of action of the force,
- \( \theta \) is the angle between \( F \) and \( r \).
Since all forces are perpendicular to their respective \( r \)-distances (\(\theta = 90^{\circ}\)), \(\sin(90^{\circ}) = 1\), simplifying the torque equation to:
\[ \tau = F \cdot r \]
### Detailed Calculation of Torque:
1. **Torque Due to \( F_1 \):**
- Distance (\( r \)) from the center of rotation (top left corner) to the acting point of \( F_1 \) is 2.0 m.
- \( \tau_{1} = 8.0 \, \text{N} \times 2.0 \, \text{m} = 16.0 \, \text{Nm} \) (clockwise).
2. **Torque Due to \( F_2 \):**
- Distance (\( r \)) from the center of rotation to the acting point of \(](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6a5d5111-1d2a-4970-848c-d397a90063e1%2F0cf1feb5-e688-4459-b8ed-b0c3999b9eea%2Fmhf4r9h_processed.jpeg&w=3840&q=75)
