a. Draw the overall free body diagram for beam (figure 1) b. Find the reaction forces at E and the tension in the cable. c. Move the reaction forces at E and the tensile force at H to points D and G and draw the FBD of the beam with the equivalent loads in the diagram below (figure 3 ). d. Draw the shear and moment diagram for the entire beam. e. In Mechanics of Materials (ENME 220), you will use the internal moment, moment of inertia, and centroid (i.e. neutral axis) to find the bending stress in the beam. If the beams cross-section (figure 2 ) has the dimensions shown, find the location of the centroid y, and the Moment of Inertia about the centroidal axis (l.e. k ). For a Extra Credit (5 PT). In problem \#2, you found the location of the centroid, the moment of inertia, and the maximum value of the internal moment. In mechanics of materials, you will use all these values to determine the stress due to bending in the beam using the flexural formula which we briefly discussed in class. If the stress is given by the equation =IMc Where M is the maximum internal moment from your Moment Diagram, I is the moment of inertia, and c is the distance from the centroid (C) to the top (or bottom) of the beam. Using the values calculated in problem #2, calculate the stress (units are psi (lb/in2)) at the top of the beam
