For one thing, you haven't calculated the reactions at C and E. Until you do, you won't be able to construct the shear and moment diagrams.

If I am interpreting what you posted correctly, you have all of your reaction at E and none at C. Why?

Cx= 0 b/c there are no other forces in the x direction. Ey = 2.43 from sum of moments, and Cy = 0 after plugging into sum of the forces in the y direction. I thought this was strange to have no reactions at C, but don't know what I could have messed up with that part.

Statics Shear Force and Bending Moment Diagrams Problem


Sorry, but if you take the reaction at E = 2.43 kN and a zero reaction at C, the beam is NOT in equilibrium because there is a net moment around C.
