Question

Check Stability and Determinacy, then determine the forces in all bars of the trusses. Indicate tension or compression. 

In the provided truss diagram, the structure consists of a series of beams connected at points labeled A, B, C, D, and E. The truss supports three vertical loads and is anchored at points A and D.

### Description of Loads:
- **Point B:** A downward force of 36 kips.
- **Point C:** A downward force of 36 kips.
- **Point E:** A downward force of 60 kips.

### Beam Configuration:
- The truss is a triangular structure with horizontal and angled beams.
- The total span of the beams from point A to point C is 60 feet.

### Measurements and Layout:
- **Horizontal Distances:**
  - From A to B: 22.5 feet
  - From B to E: 7.5 feet
  - From E to D: 15 feet
  - From D to C: 15 feet

- **Vertical Distance:**
  - From point C to the midpoint of the lower supporting beam: 20 feet

### Support:
- The truss is supported by a pin at point A and a roller at point D, allowing horizontal movement at D.

This truss diagram is typically used in engineering to calculate the forces in individual members, determining whether they are in tension or compression. These calculations help ensure the structure's integrity under the specified loads.
