The Paul JK Company designs custom lifting devices. The winch shown in Figure 12.46 was designed to lift a weight, W, of 1 200 lbf. The weight of the boom AB may be neglected for this analysis. The cable is reeled in and out at C. Find the magnitudes of cable tension T and the resultant pin reaction at A.

The Paul JK Company designs custom lifting devices. The winch shown in Figure 12.46 was designed to lift a weight, W, of 1 200 lbf. The weight of the boom AB may be neglected for this analysis. The cable is reeled in and out at C. Find the magnitudes of cable tension T and the resultant pin reaction at A.
Transcribed Image Text:The image presents a structural diagram of a mechanism involving a beam supported by a cable. Here's a detailed explanation of the diagram:
1. **Components:**
- **Beam AB:** The beam is inclined at an angle, connecting point A to point B.
- **Cable BC:** A cable is attached from point B on the beam to point C on a vertical wall.
2. **Dimensions:**
- **Length of the Beam (AB):** 6.0 feet.
- **Height from A to C:** 8.0 feet.
- **Horizontal distance from B to C:** 2.0 feet.
3. **Angles:**
- The angle θ between the horizontal line from A and the beam AB is 35 degrees.
4. **Force:**
- A downward force W is acting on point B.
This setup illustrates the application of forces and moments in structural systems, useful for studying equilibrium, tension in cables, and the effect of forces in engineering contexts.
