**Part 5**

Enter the maximum positive and negative bending moments for the beam. One method for determining these would be to begin by drawing shear-force and bending-moment diagrams for the beam on a piece of paper. Be sure to use the sign conventions from Section 7.1. Determine the maximum positive and negative bending moments from your bending-moment diagram. The "maximum negative bending moment" is the negative bending moment with the largest magnitude. Enter the maximum negative moment as a negative value here.

- **Answers:**
  - \( M_{\text{max}+} = \) [Input Field] lb-ft
  - \( M_{\text{max}-} = \) [Input Field] lb-ft

### Beam Analysis for Engineering Education

A channel shape is used to support the loads shown on the beam. The dimensions of the shape are also shown. Assume:

- \( L_{AB} = 3 \) ft,
- \( L_{BC} = 9 \) ft,
- \( P = 2300 \) lb,
- \( w = 1100 \) lb/ft,
- \( b = 16 \) in.,
- \( d = 10 \) in.,
- \( t = 0.500 \) in.

Consider the entire 12-ft length of the beam and determine:
- (a) the maximum tension bending stress at any location along the beam, and
- (b) the maximum compression bending stress at any location along the beam.

#### Diagram and Description

**Diagram Components:**
1. **Beam Diagram:**
   - A horizontal beam is shown resting on supports at points A and C.
   - A downward point load \( P \) is applied at the leftmost end, and a uniform distributed load \( w \) acts across the distance leading to point C.
   - \( L_{AB} \) is the distance between points A and B, and \( L_{BC} \) is the distance between points B and C.

2. **Cross-Sectional View:**
   - Displays the shape of the channel used for the beam.
   - Labeled dimensions include:
     - Width (\( b \)) of the channel.
     - Height (\( d \)) of the vertical stems of the channel.
     - Thickness (\( t \)) of the channel material.

#### Cross-Sectional Area Analysis
The cross-sectional area is divided into three parts:

1. **Top Horizontal Flange:**
   - Rectangular cross-section: \( 16 \) in. x \( 0.500 \) in.

2. **Left Vertical Stem:**
   - Rectangular cross-section: \( 0.500 \) in. x \( 9.5 \) in.

3. **Right Vertical Stem:**
   - Rectangular cross-section: \( 0.500 \) in. x \( 9.5 \) in.

#### Centroid Calculation Instructions

To find the areas and the centroid locations in the y-direction for each part, follow these steps:
- Enter the centroid locations, \( y_1, y_2, \) and \(
