EA CLearning Goal: To determine an l-beam's maximum bending moment, moment of inertia using the paralel-axis theorem, and the maximum stress at a given location using the flexure formula As shown, I-beam ABC supports a sign having a mass of S= 11 kg The l-beam is 740 mm long and is further supported by a rod that is attached 420 mm from the wall. Assume that all forces acting on the l-beam act along its centroid and that the l-beam's weight is negligible. Let the dimensions of the l-beam be w = 90 mm g= 25 mm, h = 70 mm j= 25 mm, c= 110 mm B 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 -bam. Drew the free-bady 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.
