Example 10.37. The deflection of a beam is governed by the equation q122 day 7 + 8ly = o(x), where Q(x) is given by the table dxt. 1/3 2/3 Q(x) : 81 162 243 and boundary condition y(0) = y(0) = y"(1) = y" (1) = 0. Evaluate the deflection at the pivotal points of the beam using three sub-intervals. 78 Example 10.37.
