![### Problem Statement
For the beam and loading shown, design the cross section of the beam, knowing that the grade of timber used has an allowable normal stress of 13 MPa. (Round the final answer to one decimal place.)
### Diagram Description
The diagram shows a simply supported beam with a uniformly distributed load. The load is 3 kN/m over the entire span of the beam.
#### Beam Details:
- **Supports**: The beam is simply supported at points A and B.
- **Span**: The distance from A to B is 2.4 m, and from B to C is 1.2 m, making the total span 3.6 m.
- **Cross Section**: The beam has a rectangular cross-section with a height of 150 mm and a width denoted as \( b \).
### Calculation Requirement
The problem requires calculating the width \( b \) of the beam so that the timber can sustain the given load without exceeding the allowable normal stress of 13 MPa.
### Question
The required value of \( b \) is [blank] mm.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F20f91b20-384f-406f-a619-71f1b1f8c76e%2Fa9875397-9d08-4b2f-9e59-e1275836df5c%2Fdzwm9n7_processed.png&w=3840&q=75)
