Question

Consider (figure). Assume F = 800 lb.

Part A: Determine the normal force acting at a section passing through point C.

Part B: Determine the shear force acting at a section passing through point C.

Part C: Determine the moment acting at a section passing through point C.

The diagram depicts a structural beam subjected to various forces and angles.

- The beam is supported at two points, labeled \( A \) and \( B \), which are connected to the ground.
- The beam forms an inverted V shape with two equal arms meeting at an apex where force \( F \) is applied vertically downward.
- On the left side of the beam:
  - A force of 800 lb is applied at a distance of 3 ft from the apex.
  - This segment of the beam is inclined at an angle of 30° relative to the horizontal.
  - Point \( C \) is located halfway at 1.5 ft from \( A \).

- On the right side of the beam:
  - A force of 600 lb is applied at a distance of 1 ft from the apex.
  - The right segment of the beam is also inclined at an angle of 30° relative to the horizontal.
  - Point \( D \) is 2 ft from the apex and 3 ft from point \( B \).

Distances and forces are clearly annotated, providing necessary data for analyzing the equilibrium and structural stability of the beam system.
