Question

Calculate normal force, sheer force, and moment at both points C and D.

## Problem 7.18

The beam is supported at \( A \) and \( B \) as shown in **Figure 1**. Suppose that \( F = 7.5 \) kip and \( w = 600 \) lb/ft. Follow the sign convention.

### Figure Description

The figure illustrates a beam that is supported at two points, \( A \) and \( B \). 

- A force \( F \) of 7.5 kip is applied horizontally on the left side of the beam, 3 feet from the end.
- There is a uniformly distributed load \( w \) of 600 lb/ft acting across the beam, starting 4 feet from the left and ending 4 feet from the right.
- The beam spans horizontally with the following segment measurements: 
  - From the left end to the start of the load is 4 feet.
  - Between point \( C \) (under the start of the load) and point \( A \) is 4 feet.
  - Between point \( A \) and \( D \) (under the load) is 6 feet.
  - From point \( D \) to point \( B \) is 4 feet.

This setup follows the standard sign convention for beam analysis.
