What is Ma, with the wrench inclined at a 3 in 4 slope?

### Image Transcription for Educational Website:

**Problem Statement:**
2.13 What is \( M_A \) with the wrench inclined at a 3 in 4 slope?

**Diagram Description:**
The diagram illustrates a wrench subjected to a force of 25 pounds (\( F = 25 \text{ lb} \)). The length of the wrench is shown to be 15 inches. The force is applied at the end of the wrench which is inclined at a slope of 3:4 (3 inches vertical for every 4 inches horizontal).

**Details:**
- The force \( F \) is represented by a downward arrow at the end of the wrench.
- The wrench is inclined at an angle such that the vertical rise over run is 3:4.
- Point A is indicated at the opposite end of the wrench from where the force is applied.
- Distance components are provided:
   - The total length of the wrench from point A to the point of applied force is 15 inches.
   - The horizontal distance component (run) is labeled as 4 units.
   - The vertical distance component (rise) is labeled as 3 units.
  
The goal is to calculate the moment \( M_A \) about point A.

**Note on Moment Calculation:**
Moment \( M \) about a point is given by the perpendicular distance from the point to the line of action of the force multiplied by the magnitude of the force.

\[ M_A = F \times d \]

Where \( d \) is the perpendicular distance from point A to the line of action of the force.

To resolve this problem, the vertical and horizontal components of the forces and distances can be used, taking into account the slope provided.

---

For educational purposes, it is important to understand the principles of calculating moments and how the inclination of the wrench affects these calculations.
