7) A light (massless) rod of length L = 1.5 m is freely pivoted at one end. Three forces act as shown
in the figure below. The force F3 acts at the midpoint. What is the torque due to each force? Take
F1 = 6.90 N, Fz = 4.00 N, F3 = 2.00 N, 0 = 20°, and a = 30°

![**Problem Description:**
A light (massless) rod of length \( L = 1.5 \, \text{m} \) is freely pivoted at one end. Three forces act as shown in the figure below. The force \( \vec{F}_3 \) acts at the midpoint. What is the torque due to each force? The given values are:
- \( F_1 = 6.90 \, \text{N} \)
- \( F_2 = 4.00 \, \text{N} \)
- \( F_3 = 2.00 \, \text{N} \)
- \( \theta = 20^\circ \)
- \( \alpha = 30^\circ \)
**Diagram Explanation:**
- The rod is pivoted vertically on the left.
- Force \( F_1 \) is applied at an angle \(\alpha\) from the rod.
- Force \( F_2 \) acts horizontally at the end of the rod.
- Force \( F_3 \) is applied vertically downward at the midpoint of the rod.
- The lengths and angles are labeled as follows: \( F_2 \) acts at the full length \( L = 1.5 \, \text{m} \), and \( F_3 \) acts at \( \frac{L}{2} = 0.75 \, \text{m} \).
**Torque Calculation:**
Torque \(\tau\) due to a force is calculated using the formula:
\[
\tau = r \cdot F \cdot \sin(\theta)
\]
Where:
- \( r \) is the lever arm length from the pivot.
- \( F \) is the force magnitude.
- \( \theta \) is the angle between the force and lever arm.
Apply this formula for each force:
1. **Torque due to \( F_1 \):**
\[
\tau_1 = L \cdot F_1 \cdot \sin(\alpha)
\]
2. **Torque due to \( F_2 \):**
\[
\tau_2 = L \cdot F_2 \cdot \sin(\theta)
\]
3. **Torque due to \( F_3 \):**
\[
\tau_3 = \frac{L}{2} \cd](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fee22cf2f-b974-4b00-a3cf-09b388e7d65d%2Fce7aba24-e8e4-45af-829d-bc626702b1e7%2Fj67tesn_processed.jpeg&w=3840&q=75)
