Learning Goal:

To determine an l$-$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.

dimensions of the I$-$beam be $w=3in.,g=0\mathrm{.}9in.,h=2in.,j=1$ in$.,c=6$ in$.$

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 l$-$beam. Draw the free$-$body diagram of beam ABC. upward.
