### Application of Tension Members in Structural Engineering A **C9×20** steel section is selected for use as a tension member, as illustrated in Figure 1. The tension member is connected to a gusset plate (thickness: 3/8 inch) using A307 bolts with a diameter of 1 inch. The tension member itself is made from A572 Grade 50 steel, whereas the gusset plate is crafted from A36 steel. #### Objectives: 1. **Spacing and Edge Distance Requirements** - Analyze and verify that all bolt spacings and edge distances conform to the specified standards. 2. **Design Strength Calculations** - Compute the design strength of the tension member based on factors such as shear and bearing capacities, considering the specified material properties and specifications outlined. #### Figure 1: The schematic presented in Figure 1 illustrates the layout of the tension member, the bolt positioning, and the dimensions relevant to the analysis: - The tension member (a channel section identified as **C9×20**) has a thickness **t = 3/8 inches**. - Bolt holes are arranged with horizontal spacing of **3 inches** and vertical spacing of **2 inches** between adjacent bolts. - The edge distance from the center of the bolt hole to the edge of the member is **2 inches** along both horizontal and vertical edges. The diagram also indicates the positions and dimensions relevant to assessing the criteria outlined. By following the given objectives and using the information from the diagram, you can proceed to check all spacing and edge distance requirements and then compute the design strength based on shear and bearing for the specified tension member.
