iniform simply supported beam, span Z, carries a distributed loading which varies according to a parabolic law across the span. The load intensity is zero at botch ends of the beam and w, at its mid- point. The loading is normal to a principal axis of the beam cross section and the relevant flexural rigidity is EI. Assuming that the deflected shape of the beam can be represented by the series inx a; sin L find the coefficients a; and the deflection at the mid-span of the beam using only the first term in this series.
