Question

Draw the shear and moment diagrams for the diving board, which supports the 155-lb man poised to dive. Then answer the questions. The distance x is measured from point A to the right.
Assume a = 43 in., b = 10 ft.

The largest bending moment (absolute value) that occurs in the board is.

**I cannot figure out the last part of the question., finding the largest bending moment that occurs in the board. Could you also graph the shear and bending diagrams for this problem?

The image displays a diagram of a diving board with a 155-lb person positioned to dive. The setup includes two supports marked as A and B. The distance from point A to B is measured as \( a = 43 \) inches and \( b = 10 \) feet. The horizontal distance \( x \) is measured from point A to the right.

### Questions:

1. **At \( x = 10 \) in:**
   - Shear Force (\( V \)) = \(-277.56\) lb
   - Bending Moment (\( M \)) = \(-231.30\) lb-ft

2. **At \( x = 60 \) in:**
   - Shear Force (\( V \)) = \( 155 \) lb
   - Bending Moment (\( M \)) = \(-774.997\) lb-ft

3. **The largest bending moment (absolute value) that occurs in the board is:**
   - \( 775 \) lb-ft 

### Description:

The figure suggests analyzing the mechanical response of the diving board under the load of the person. The calculated values illustrate the effects of the person's weight at specific distances along the board. The biggest bending moment indicates the point of maximum stress on the board.
