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. 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. View Available Hints) No elements selected L. B .C Select the elements from the list and add them to the canvas setting the appropriate attributes.
Part B - Moment of inertia of beam ABC Determine the moment of inertial of l-beam ABC. Recall that in an l-beam, the flanges are the horizontal top and bottom sections and the web is the vertical section between the two flanges. - Express your answer to three significant figures and include the appropriate units.
