### Problem Statement

A vertical tower truss shown below is supporting a water tank and is also subjected to horizontal wind loads. Compute the forces for members AB, AE, and BE.

### Diagram Description

The diagram depicts a structural analysis of a vertical tower truss:

- The truss is fixed at the base points A and F.
- It is divided into three horizontal levels: C to D, B to E, and A to F.
- **Vertical Elements**: 
  - AD and BF are vertical members of the truss.
  
- **Horizontal Members**:
  - CD and EF connect the vertical elements.
  
- **Diagonal Members**: 
  - AC, BE, and DB are diagonal cross members.

- **Loads**:
  - Two vertical loads: 20 kips (k) are applied at points C and D.
  - Two horizontal wind loads: 3 k each are applied at points C and B from the left.

- **Dimensions**:
  - Horizontal distance for CD and EF is 6 feet.
  - Vertical distance for AC and BE is 8 feet.
  - The diagonal members have varied lengths due to the geometry.

This problem involves calculating the forces in the members AB, AE, and BE under these load conditions using static equilibrium and methods suitable for truss analysis, such as the method of joints or the method of sections.
