Determine the force in each member of the truss shown in (Figure 1). State if the members are in tension or compression. Take that P = 420 lb.

Express your answer to three significant figures and include the appropriate units. Assume positive scalars for members in tension and negative scalars for members in compression. 

Given: angle to use is 36.9 degrees, FCD = 700lb FAD =-560lb  

Find: 

a) Determine the force in the member BC of the truss, and state if the member is in tension or compression. 

b)  Determine the force in the member AC of the truss, and state if the member is in tension or compression. 

c) Determine the force in the member AB of the truss, and state if the member is in tension or compression.

 

 

**Title: Loading Acting on a Truss**

**Description:**

The image illustrates a structural truss with a load applied. The truss is composed of multiple members connected at joints. It is a part of a structural analysis study, looking at how forces are distributed in a truss system.

**Diagram Details:**

- **Truss Members:** The truss consists of members AB, AC, AD, BC, and CD.
- **Joints:** The truss features joints at points A, B, C, and D.
- **Dimensions:** 
  - Horizontal distance between joints A to C and C to D is 2 feet each.
  - Vertical distance from joint A to line BC is 3 feet.

- **Support Structure:**
  - At joint A, there is a roller support allowing horizontal movement.
  - At joint B, a fixed support (denoted by two vertical lines and a rectangle) restricts movement in any direction.

- **External Load:**
  - A downward load \( P \) is applied at joint D. 

Use this diagram to analyze the forces acting on each member of the truss and understand how structural loads are carried in a truss system. The truss is symmetric, and understanding the equilibrium at each joint can help solve for internal forces within each member.
