Plane and Space Trusses

In civil engineering, a truss is the most important structure that forms the most fundamental member of any building structure and commercial complexes. Trusses are composed of individual members or links that are interconnected by suitable joints, such as rivets, welds, or bolts, and nuts. In trusses, the interconnection leads to the formation of a series of triangles joined together such that all the triangular members behave as a single rigid body. In a simple truss, three members are connected to form a truss member. In trusses, the force always acts at the joints or the interconnection between the individual members.

Question

**Problem Statement:**

Determine the largest load \( P_2 \) that can be applied to the truss so that the force in any member does not exceed 500 lb (Tensile) or 350 lb (Compressive). Take \( P_1 = 0 \).

**Truss Description:**

- **Type:** Simple truss with a pinned support at point B and roller support at point A, forming a structurally stable framework.
- **Configuration:** The truss consists of four main joints labeled A, B, C, and D, forming a rectangular shape with additional cross-bracing members.
- **Dimensions:**
- Horizontal span (between A and D) is 12 ft.
- Vertical distance (between B and C) is 5 ft.

**Members:**

The truss has the following members:

- Horizontal members: AB (support at B) and CD.
- Vertical members: AD and CB.
- Diagonal cross-bracing: AC and BD.

**Load Conditions:**

- **P2:** A vertical downward load applied at joint D.
- **P1:** Horizontal load, taken as 0 for this analysis.

**Objective:**

Calculate the maximum permissible \( P_2 \) while ensuring that:

- No member has a tensile force exceeding 500 lb.
- No member incurs a compressive force greater than 350 lb.
