Question

**Problem 3-21**

Determine the force in members \(FC\), \(BC\), and \(FE\). State if the members are in tension or compression. Assume all members are pin connected.

**Diagram Explanation:**

This is a truss structure with several members forming a pinned frame:

- **Members and Points:**
- The members are labeled as segments joining the points \(A\), \(B\), \(C\), \(D\), \(E\), and \(F\).
- The points are connected to form triangular and rectangular shapes.

- **Loads:**
- A vertical load of \(1.5 \, \text{k}\) is applied downward at point \(F\).
- A vertical load of \(2 \, \text{k}\) is applied downward at point \(E\).

- **Dimensions:**
- The horizontal distance between points \(A\) to \(B\), \(B\) to \(C\), and \(C\) to \(D\) is \(8 \, \text{ft}\) each.
- The vertical distance from the base level up to point \(F\) and \(E\) is divided into three segments, each \(6 \, \text{ft}\) high.

The task is to calculate the forces in specific members and determine whether these forces are causing tension (pulling apart) or compression (pushing together).
