In order to determine the magnitude of the internal forces, a FBD must be cut. It is difficult to determine where a cut should be made in order to reveal the Maximum Internal Forces, thus we have put the distance to the cut in terms of 'x', and plot the equation. In my lecture we took a generic portion of a Beam and applied equilibrium and saw that Loading, Shear and Moment are related to each through differential equations. Change in Shear is the Area under the Loading diagram. Change in Moment is the Area under the Shear Diagram. Using Graphic Integration draw the shear and moment diagrams for the given beams and loading.

Im doing a shear and moment calculation for a problem graphically and keep getting a negative sign in my moment calculation where I should be getting a postive sign. I know that the integral of my shear calculation is going to be my moment equation but I always use this to "check" myself against my work after I do my standard summation of moments about a point. I KNOW I SHOULD be getting M_2(x) = -.5x^2 + 2x + c but as you can see by my work I keep getting a "-2x". Why is this and where am I going wrong?
