Transcribed Image Text:### Howe Scissors Roof Truss Analysis
#### Diagram Description
The image illustrates a Howe scissors roof truss. The truss is supported at two points, A and L, with vertically applied loads labeled \( P_1 \) and \( P_2 \). The loads are distributed along the truss as follows:
- \( P_1 = 0.9 \) kips
- \( P_2 = 1.8 \) kips
The truss spans several members connected at joints from A to L, with equal segments of 8 feet between joints B through K and segment 4.5 feet between K and L. The vertical distances are 6 feet from F to the bottom chord and 4.5 feet elsewhere.
#### Forces in Truss Members
Determine the forces in members DF, DG, and EG under the shown loading conditions:
1. **Member DF:**
- Force: 14.65 kips
- Type: Tension
2. **Member DG:**
- Force: 0.9 kips
- Type: Tension
3. **Member EG:**
- Force: 15.718 kips
- Type: Compression
The analysis assumes equilibrium and applies static principles to understand the distribution of forces within the truss structure.
