A simply-supported beam illustrated in Figure 5.1 is subjected to a uniformly distributed load w. The flexural stiffness of the middle-half of the span is doubled to reduce the midspan deflection. Determine (a) the deflection at the midspan, (b) the slope at the supports, and (c) the maximum w that can be applied if the maximum allowable deflection is L/360.
