Transcribed Image Text:### Problem Description:
A 100-kg cylinder is hung by means of two cables AB and AC that are attached to the top of a vertical wall. A horizontal force \( P \) perpendicular to the wall holds the cylinder in the position shown. Determine the magnitude of \( P \) and the tension in each cable.
### Diagram Explanation:
The diagram shows a system in which a 100-kg cylinder is suspended by cables from a wall. The key elements of the diagram are as follows:
- **Cylinder:** Located at point \( A \) and labeled as 100 kg.
- **Cables AB and AC:** The cables are attached to the wall at points \( B \) and \( C \) and support the cylinder at point \( A \).
- Cable \( AB \) is 6 meters long from point \( B \) (on the vertical wall) to point \( A \).
- Cable \( AC \) is 5 meters long from point \( C \) (higher on the wall and horizontally distant) to point \( A \).
- **Horizontal Force \( P \):** This force acts horizontally to the right from point \( A \).
- **Dimensions:**
- Horizontal distance from the wall to point \( A \): 0.6 meters.
- Vertical distance from cable attachment \( B \) to \( A \): 6 meters.
- Horizontal distance from cable attachment \( C \) to \( B \): 4 meters.
- Horizontal distance from the wall to the point where \( P \) is applied: 1 meter.
### Detailed Explanation:
To solve for the magnitude of \( P \) and the tension in each cable, we need to establish the forces in equilibrium. The weight of the cylinder exerts a downward force due to gravity. The tensions in cables AB and AC must counteract this weight and also the horizontal force \( P \). Using principles of static equilibrium (sum of forces in x and y directions equals zero and sum of moments equals zero), we can set up equations to solve for the unknowns.
### Mathematical Formulation:
Let \( T_{AB} \) be the tension in cable AB, and \( T_{AC} \) be the tension in cable AC.
#### 1. Sum of Forces in X-direction:
\[ T_{AB} \cdot \sin(\theta_1) + T_{AC} \cdot \sin(\theta_2
