Question

What is the force in member ED, EH, and EG if
F1 = 29 lbs, F2 = 35 lbs, F3 = 23 lbs. F4 = 63 lbs.
State whether each member is in Tension (T) or
Compression (C).

### Structural Truss Diagram with Applied Forces #### Overview This diagram illustrates a structural truss with several joints and applied forces, labeled as \( F_1, F_2, F_3, \) and \( F_4 \). The truss consists of a series of interconnected beams, forming a supportive framework often used in construction and engineering. #### Description and Measurements - **Joints and Points:** - The truss connects at various points labeled as \( A, B, C, D, E, F, G, H, \) and \( I \). - Joints \( F \) and \( A \) are grounded with supports. - **Force Applications:** - \( F_1 \) and \( F_2 \) are vertical downward forces applied at points \( E \) and \( D \), respectively. - \( F_3 \) and \( F_4 \) are horizontal forces directed to the left, applied at points \( C \) and \( B \). - **Beam Lengths:** - The horizontal distances between points \( E \) to \( D \), and \( D \) to \( C \) are each 2 meters. - The vertical sections from \( C \) to \( B \), and \( B \) to \( A \) are each 1.5 meters. #### Structural Composition - The truss is designed in a combination of triangular and rectangular shapes, maximizing its ability to bear loads efficiently. - A triangular shape is formed between joints \( E, D, \) and \( G \), as well as between \( D, C, \) and \( H \). #### Practical Application Truss designs like this are common in bridges and roof supports, where they help distribute loads evenly across the structure, minimizing stress on any single point.
