Question
**Problem Statement:** The 3-inch I beam below has cross-sectional properties of \(A = 1.64 \, \text{in}^2\), \(I_{11} = 2.5 \, \text{in}^4\), and \(I_{22} = 0.46 \, \text{in}^4\). It is made of steel having \(S_y = 60 \, \text{ksi}\). Find the safe axial compressive load based on a safety factor of SF = 4 for pinned ends and unsupported lengths of: a) 10 in, b) 75 in, c) 125 in, and d) 250 in. **Diagram Description:** The diagram is a simple illustration of an I-beam. It consists of two horizontal sections (flanges) connected by a vertical section (web). The I-beam is labeled with axis lines: - The horizontal axis is labeled as 1-1. - The vertical axis is labeled as 2-2. This setup is typical for evaluating the structural properties of I-beams including calculations related to stress and buckling under axial loads.
