### Educational Resource on Structural Engineering **Example Problem 6.13** **Objective:** Determine the largest allowable vertical shear in a beam with attached plates, given that the shearing stress should not exceed 90 MPa. **Description:** Two steel plates of dimensions 12 mm by 200 mm are welded onto a W310 x 52 beam. The goal is to calculate the maximum vertical shear force permissible without surpassing the shearing stress limit of 90 MPa in the beam. **Diagram Explanation:** - The diagram illustrates a cross-sectional view of the beam setup. - The central component is labeled “W310 x 52,” representing a standard steel I-beam. - Two additional rectangular plates, each with a cross-section of 12 mm by 200 mm, are welded to the flanges of the I-beam. - The configuration forms a composite section aimed at enhancing certain mechanical properties, such as stiffness and load-bearing capacity. **Calculation Approach:** To solve, one must: 1. Calculate the shear stress distribution across the beam, considering both the I-beam and the attached plates. 2. Ensure that the computed shear stress remains below or equal to the 90 MPa limit. This example provides practical insight into how additional materials can reinforce structural elements while maintaining stress within safe levels.
