**Problem Statement:**

8. Rod \( AB \) is fixed to a smooth collar \( D \), which slides freely along the vertical guide. Determine the normal force, shear force, and moment at point \( C \), which is located just to the left of the 60 lb concentrated load.

**Diagram Explanation:**

- The diagram shows a rod \( AB \) with a length of 6.5 ft.
- The rod is positioned horizontally with end \( A \) attached to collar \( D \).
- Collar \( D \) can move freely along a vertical guide.
- There is a uniformly distributed load of 15 lb/ft on the rod running from \( A \) to \( B \).
- A concentrated load of 60 lb is applied vertically downward at a point \( 1.5 \) ft from \( B \).
- Point \( C \) is located 5 ft from \( A \) and is to the left of the concentrated load.
- At end \( B \), the rod is oriented at an angle of \( 30^\circ \) with respect to the horizontal. 

**Detailed Analysis:**

- To analyze the forces at point \( C \), consider:
  - The distributed load creates a linear force along the rod between \( A \) and \( B \).
  - The concentrated load contributes to the vertical force at point \( C \).
  - Balance of moments and forces needs to be calculated to solve for shear force, normal force, and bending moment at \( C \).
