Question
## Analysis of a Flanged Wooden Beam

A flanged wooden shape is used to support a series of loads. The following considerations are made over the entire 16 ft length of the beam. The tasks are to determine:

### (a) Calculate the Inertia
- **Task**: Determine the moment of inertia for the beam section.

### (b) Sketch the Shear and Moment Diagram for the Beam
- **Task**: Create diagrams that depict the shear forces and bending moments along the beam.

### (c) Maximum Tensile Bending Stress in the Beam
- **Task**: Calculate and illustrate the maximum tensile bending stress, with detailed calculations of this stress distribution.

### (d) Maximum Compressive Bending Stress in the Beam
- **Task**: Calculate and illustrate the maximum compressive bending stress, with detailed calculations of this stress distribution.

### (e) Maximum Shear Stress in the Beam
- **Task**: Calculate and sketch the shear stress distribution, showing detailed calculations.

### Diagram Explanation

#### Beam Setup
- **Support Configuration**: 
  - A pin support at point A.
  - A roller support at point D.
- **Load Distribution**:
  - A 1 kip/ft distributed load from A to B (6 ft span).
  - A concentrated load of 2 kips at point C (3 ft from B).
  - A concentrated load of 2.2 kips at point E (4 ft from D).

#### Cross-Section Diagram
- **Dimensions**: 
  - Total height: 12 in.
  - Widths:
    - Flange: 8 in at base, 4 in at top.
  - Thicknesses:
    - Flange: 1 in.
    - Web: 1 in.
- **Segments**:
  - (1) Top flange: 4 in width
  - (2) Web: 10 in height
  - (3) Bottom flange: 8 in width

These details are critical for performing structural analysis on the beam to ensure it can safely sustain the applied loads.
