1. The problem statement, all variables and given/known data Draw the shear and moment diagrams for the beam shown and find the bending moment M at section C. 3. The attempt at a solution So I got the correct answer for Mc but I'm confused on a few things. I get different answers using different techniques for different aspects of this problem. Take my shear diagrams for example. You can see two sections to the lower right trying to calculate shear in between forces (I wanted to confirm between techniques) but they aren't adding up. 1.5' to the right of the 1000lb downward force, the shear should be 1000 up right? If I cut it into a section? But it doesn't coincide with my diagram. Also, if I add up all the areas under my shear lines, I get -730.9. Shouldn't I get 0? BTW, I know my moment diagram is off, I have since changed it but dont have the copy to scan, this is an old copy.
