5. Draw the moment diagram for the beam subjected to the loading conditions shown in the Figure below. Note that the shear diagram is provided. Indicate the moment values throughout the beam. For each segment, specify the moment value at the beginning and end of the segment. Also, specify the moment value at any peak(s). Specify the x-location of any peak(s). Show if the curves are concave up or concave down. If this is difficult to illustrate on your diagrams, make a side note to clarify. Show all your work and calculations. Upload together with other solved problems at the end of this exam.

2. For the composite cross-section shown in problem 1, determine the second moment of area (I) about the neutral axis (N.A.) which for this problem will be assumed to be located 35 mm above the x-axis. Note: The 35 mm to the neutral axis may not be what you found in problem 1, but you should proceed with that value for this problem. Show all your work. Upload together with other solved problems at the end of this exam.
