![**Learning Goal:**
To determine an I-beam's maximum bending moment, moment of inertia using the parallel-axis theorem, and the maximum stress at a given location using the flexure formula.
As shown, I-beam \( ABC \) supports a sign that weighs \( S = 30 \, \text{lb} \). The I-beam is 24 in. long and is further supported by a rod that is attached 18 in. from the wall. Assume that all forces acting on the I-beam act along its centroid and that the I-beam's weight is negligible. Let the dimensions of the I-beam be \( w = 4 \, \text{in.}, \, g = 0.8 \, \text{in.}, \, h = 2.9 \, \text{in.}, \, j = 1 \, \text{in.}, \, c = 6 \, \text{in.} \)
**Diagram Explanation:**
The diagram shows an I-beam \( ABC \) attached to a wall at point \( A \) with a rod \( ACD \) supporting a sign of weight \( S \) hanging from it. The I-beam’s length and its positions relative to the wall are annotated, as are the dimensions of the I-beam's cross-section.
**Part A - Free-body diagram of beam \( ABC \):**
Before the problem can be analyzed, a free-body diagram must be drawn to understand the forces and reactions that act on the I-beam. Draw the free-body diagram of beam \( ABC \).
A free-body diagram includes the forces acting on the object, in this case the beam. Start your vectors at the black dots. You will not be graded on vector length. Ignore all reaction forces in the \( x \) direction, and assume all vertical reaction forces point upward.
