Question

find largest shearing stress

For the beam and loading shown, determine the largest shearing stress in section \( n-n \). Take \( P = 214 \, \text{kN} \).

**Diagram Explanation:**

- **Left Diagram**: Shows a simply supported beam with supports at points \( A \) and \( B \). The beam length is divided into three segments: the left and right segments are each \( 0.75 \, \text{m} \), and the middle segment is \( 1.2 \, \text{m} \) long. Two vertical forces \( P \) are applied symmetrically on the beam.
  
- **Right Diagram**: Displays the cross-sectional view of the beam at section \( n-n \). The cross section resembles an inverted "T" shape, with dimensions:
  - Overall height: \( 150 \, \text{mm} \)
  - Top flange thickness: \( 50 \, \text{mm} \)
  - Web width: \( 75 \, \text{mm} \)
  - Flange width: \( 75 \, \text{mm} \)
  - Bottom flange height: \( 50 \, \text{mm} \)
  
The circles labeled \( a \) and \( b \) in the web section likely indicate points of interest for shearing stress calculation.
