You must provide the value of X. For example, if the answer is enter "0.05" (1/20) in the Canvas quiz.

Here are a few hints. You'll have to break up the integral over three segments (A to B, B to C, and C to D). On several spans, one of the moment diagrams will be zero.
Remember that the definite integral of zero is equal to zero, i.e., " Odx
0. All the remaining integrals should involve triangles with integration factors of 1/3 and 1/6.
