### Bolted Connection Analysis A bolted connection is shown in the diagram. It is bolted with A-325 bolts with an allowable shearing stress of 207 MPa. A-36 steel is used. The applied force "T" is equally divided among the bolts. Assume the bolt hole diameter to be 3 mm larger than the bolt diameter. The diameter of the bolt is 20 mm. **Dimensions:** - Bolt hole diameter: 23 mm (3 mm larger than bolt diameter) - Plate width: 300 mm - Edge distance: 10 mm from each side **Objective:** Determine the efficiency of this bolted connection in percentage. **Options:** - A: 90.15% - B: 93.19% - C: 94.58% - D: 90.61% **Diagrams Explained:** 1. **Top Diagram (Side View):** - Illustrates the side view of the bolted plates. - Forces "T/2" are applied at each side, indicating that the load is split equally. - The bolts are represented as dashed lines across the section. 2. **Bottom Diagram (Top View):** - Displays the top view of the connected plates. - Shows the alignment and spacing of the bolts. - Includes edge distances of 10 mm, which are crucial for ensuring structural integrity. This setup is common in mechanical and structural engineering for assessing the load capacity and safety of bolted connections in construction and machinery. Evaluate the options to determine the connection efficiency accurately.
