Consider the following beam with overhangs: A B You must provide the value of X. For example, if the answer is PL³ 20-EI C O X. PL³ EI 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 L D = P 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., f Oda 0. All the remaining integrals should involve triangles with integration factors of 1/3 and 1/6.
