A simply supported beam AB of span L and uniform section carries a distributed load of intensity varying from zero at A to w,Junit length at B according to the law 2w,x w=- L 2L per unit length. If the deflected shape of the beam is given approximately by the expression 2nx v= aj sin-+a2 sin- L L evaluate the coefficients aj and a, and find the deflection of the beam at mid-span. Ans. a,-2w,Lª (x’+4)/Eln", az--w,L*/16EIn*, 0.00918w,L*/EI.
