### Problem 5

Classify each of the following trusses as statically determinate, statically indeterminate, or unstable. If indeterminate, state its degree.

**Diagram Descriptions:**

- **Figure (a):** The first diagram shows a triangular truss with three joints and three members, forming a simple triangular shape.

- **Figure (b):** The second diagram displays a rectangular truss with a cross bracing and two additional supports at the top corners. It includes six joints and eight members.

- **Figure (c):** The third diagram features a horizontal truss with a pitched roof structure, composed of five joints and seven members.

- **Figure (e):** The fourth diagram is a rectangular truss on two different supports: one roller and one pinned support. It features six joints and nine members.

- **Figure (f):** The fifth diagram has a rectangular shape with cross bracing and additional vertical and horizontal members, containing six joints and eleven members.

- **Figure (g):** The sixth diagram shows a truss similar to (c) but has extra horizontal members, exhibiting the pitched roof structure and additional supports. It includes six joints and seven members.

These truss diagrams are essential for analyzing structural stability and determining whether each truss is statically determinate, indeterminate, or unstable based on the number of members, reactions, and joints.
