Question
**Q.1) Truss Analysis Using Method of Sections** The truss depicted has a pin support at point A and a rocker support at point G. Points A, B, C, D, E, F, and G are evenly spaced, each by 4 feet horizontally. a) **Force Analysis:** - Apply the Method of Sections to ascertain the force in members KJ, CJ, and CD. Indicate the magnitude of the force and specify whether the member is in tension or compression. b) **Zero-Force Members:** - Identify the members in the truss that carry zero force. **Diagram Explanation:** - The truss contains several joints and members. Loads are applied vertically at points K, J, and H with magnitudes of 100 lb, 500 lb, and 100 lb respectively (total at respective points), and two additional loads of 250 lb each are applied at points K and J. - The height from the bottom chord to the apex at point J is 6 feet. - The entire span of the truss is 24 feet. Members of note include: - Horizontal members: AB, BC, CD, DE, EF, FG - Inclined members: KL, LK, KJ, JW, IH, HG - Vertical member: DJ Use the described dimensions and forces for detailed truss analysis as required.
