Question
**Text:** The maximum average shear stress for the thin-walled section at the middle of the beam is equal to: (τ = V/A(web)) **Diagram Explanation:** 1. **Left Diagram:** - A beam is supported at two ends, labeled A and B. - Two downward forces of 1.5 kN each are applied at equal distances of 0.2 meters from a central point. - The total span between supports A and B is 0.8 meters, with the forces causing potential bending and shear in the beam. 2. **Right Diagram:** - Cross-sectional view of the beam is shown. - The shape is an I-beam with a uniform thickness of 5 mm. - The dimensions are marked as 20 mm for both the height and the length of the horizontal flanges. The thickness is consistent throughout the section. This information is used to calculate the shear stress at the web of the beam using the formula τ = V/A, where V is the shear force and A is the area of the web.
