Question
**Problem 2** The King-Post structure shown has a beam and three truss members. - \( E = 29000 \, \text{ksi} \) - \( I = 400 \, \text{in}^2 \) - \( A = 1.25 \, \text{in}^2 \) **Tasks:** 1) Determine the tension in members AC and BC. 2) Determine the maximum moment in beam ADB. **Diagram Explanation:** The diagram depicts a King-Post truss structure: - Point A is on the left and appears to be a support with a hinge. - Point B is on the right, also supported, with a roller. - The horizontal beam AB is divided into two equal lengths of 12 ft each, from A to D and D to B. - An external load of 80 kips is applied downward at point D. - Members AC and BC are inclined, both spanning from points A and B to a central bottom point C, forming two triangles with the beam, each having horizontal spans of 12 ft and vertical drops of 5 ft. The diagram is set on graph paper for clarity, with a clear indication of points and dimensions. It is used to determine the structural responses of this King-Post truss under the given load.
