We are asked to determine the magnitude of the moment about point \( B \) due to force \( F_1 = 355 \, \text{N} \). Based on the image, we need to find the moment (or torque) produced by \( F_1 \) about point \( B \).

### Key Information:
- Force \( F_1 = 355 \, \text{N} \) acts vertically downward.
- Distance from point \( A \) to point \( B \) is \( 0.8 \, \text{m} + 0.6 \, \text{m} = 1.4 \, \text{m} \).
- The perpendicular distance between the line of action of \( F_1 \) and point \( B \) is the horizontal distance from \( A \) to \( B \), which is \( 1.4 \, \text{m} \).

### Moment about point \( B \)
The formula for the moment \( M_B \) about a point is given by:
\[
M_B = F \times d_{\perp}
\]
where:
- \( F \) is the force applied,
- \( d_{\perp} \) is the perpendicular distance from the point to the line of action of the force.

Here:
- \( F_1 = 355 \, \text{N} \),
- \( d_{\perp} = 1.4 \, \text{m} \).

Thus, the moment \( M_B \) is:
\[
M_B = 355 \, \text{N} \times 1.4 \, \text{m} = 497 \, \text{N-m}
\]

### Final Answer:
The magnitude of the moment about point \( B \) is \( 497 \, \text{N-m} \).

Would you like more details or have any further questions?

Here are 5 related questions:
1. What is the physical significance of a moment or torque in mechanics?
2. How would the moment change if \( F_1 \) was applied at an angle?
3. What is the impact of adding force \( F_3 \) in this problem?
4. How do we calculate moments when forces are applied at different angles?
5. What would be the moment if the distance from \( A \) to \( B \) was changed?

**Tip**: The moment arm is the perpendicular distance from the line of action of the force to the point of rotation. Always ensure you're using this distance when calculating moments.

Determine the magnitude of the moment about point B of the force F1 = 355 N. Do not consider F3. Give your answer in N-m.

Learn how to calculate the moment about point B of the force F1 = 355 N in a simple statics problem. This solution includes the application of the moment formula M = F × d_perpendicular, where the force is perpendicular to the distance from point A to B.
