A В C L L. Calculate the deflection at A (the end opposite of the load) and at D (under the load). Assume that both deflections are downward. The answers will be of the form PL3 X. EI You must provide the value of X.For example, if the answer is , enter "0.05" (1/20) in the Canvas quiz. 20-EI 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 S° Odx = 0. All the remaining integrals should involve triangles with integration factors of zero. Remember that the definite integral of zero is equal to zero, i.e., 1/3 and 1/6.

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.
