Determine (a) the distance a for which the absolute value of the bending moment in the beam is as small as possible, (b) the corresponding moximum normal stress due to bending.

### Beam Loading Analysis

**Introduction:**

Consider the given beam and loading configuration, where the applied load \( P = 1.6 \) kips. For this analysis, the section modulus is given as \( 1.67 \, \text{in}^3 \).

**Diagram Explanation:**

- The diagram shows a horizontal beam supported by two supports: one is a triangular support (at C) on the left and the other is a roller support (at E) on the right.
- There are three vertical loads acting on the beam at points A, D, and E:
  - \( 0.8 \) kips at point A.
  - \( P \) kips (which is \( 1.6 \) kips) at point D.
  - \( 1.2 \) kips at point E.
  
- The distances between points on the beam are as follows:
  - Distance \( a \) from A to C.
  - \( 1.5 \) ft between points C and D.
  - \( 1.2 \) ft between points D and E.
  - \( 0.9 \) ft between points E and B.
  
- The cross-section of the beam is represented as "S3 x 5.7", indicating the specific size and weight of the I-beam used.

**Key Points:**

- **Section Modulus:** An important factor in determining the strength and performance of the beam under loading.
- **Support Reactions:** Calculate the reactions at supports C and E to ensure static equilibrium of the beam.
- **Analysis Objective:** Understanding how the beam will behave under the given load to ensure safe design and support placement.

This explanation and diagram can be used as a reference for structural analysis and design of beams in building construction or mechanical systems.
