Question
I know BE is a zero force member but I can't find the force applied at BD? Also state if it's in compression or tension.
![**Truss Force Calculation Example**
**Objective:**
Calculate the forces in members \( BE \) and \( BD \) of the loaded truss. The forces are positive if in tension and negative if in compression.
**Given:**
- Force \( F = 3.3 \, \text{kN} \)
- \( a = 2.4 \, \text{m} \)
- \( b = 3 \, \text{m} \)
- \( c = 2 \, \text{m} \)
- \( d = 2 \, \text{m} \)
**Diagram Explanation:**
The diagram represents a truss structure with the following components:
- A vertical force \( F \) applied downward at point \( A \).
- Members \( AB \), \( BE \), \( BD \), \( DE \), \( CD \), and \( CE \) are shown.
- Triangular sections \( \triangle ABD \) and \( \triangle BCD \) within the truss.
- Point \( A \) is connected to points \( B \) and \( E \) by horizontal members \( AB \) and \( AE \).
- Point \( D \) is connected to point \( C \), forming a vertical and diagonal connection.
**Results Section:**
- Force in \( BE = 0 \, \text{kN} \)
- Force in \( BD: \) [calculation needed]
**Note:**
Further analysis using methods like the method of joints or sections is required to calculate the force in member \( BD \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2db19295-5df8-4985-9669-b6d8605dbc2a%2F84ae4faf-928c-4ae0-8bde-fdb53ddaf99a%2Fuo76saf_processed.jpeg&w=3840&q=75)
