29. A continuous beam rests on four supports with the right-hand end rigidly fixed. The first span at the left-hand end is 6 m and carries 36 kN uniformly distributed. The second span is 9 m and carries 18 kN at the centre and the third span is 12 m carrying 12 kN uniformly distributed. Calculate the bending moments and reactions and draw the B.M. and S.F. diagrams to scale. (U. Lond.) (Ans.: Mb 24.485 kN m; Mc 15.05 kN m; Ma 10-425 kN m; Rg 13.92 kN; Rb 32.11 kN; Rc = 14.28 kN; Ra 5.69 kN)
