Question
**Zero-Force Members in Truss Structures** **Objective:** Identify all the zero-force members. Determine the force in members JK, JN, and CD. State if the members are in tension or compression. **Truss Diagram Description:** The truss structure depicted is a symmetrical arrangement with a series of interconnected members forming triangular units. It spans horizontally with a total length of 70 feet and has a vertical height of 20 feet at its highest point. **Key Features:** - **Nodes:** Significant connection points labeled from A to J. - **Members:** Bars or segments joining the nodes. Specific members of interest for force analysis are JK, JN, and CD. - **Support:** - At node A, there is a pin support allowing rotation but not translation. - At node F, there is a roller support, which allows horizontal movement. - **Loads:** - There are two downward loads of 2 kips each applied at nodes C and D, both equal and separated by 30 feet longitudinally. **Geometry:** - The entire horizontal span is divided into three sections: - AB is 20 feet. - BC is 30 feet. - CD is 30 feet. - The vertical measurements indicate the highest point of 20 feet from base point G to apex J. **Analysis Requirements:** 1. **Zero-Force Members:** Identify members in the system that do not carry any force under specific loading conditions, aiding in simplifying the truss analysis. 2. **Force Determination:** - Evaluate forces in specific members JK, JN, and CD. - Determine if these members exist in a state of tension (pulling apart) or compression (pushing together).
