Band E. The lengths of the various portions are AB 1-5m, BC = 1-5m, CD = 1 m and DE
: 3 m. There is a uniformly distributed load of 15kN/m between B and a point 2m
to the right of B and concentrated loads of 20 KN act at 4 and 0 with one of 50
KN at C. (a) Draw the S.F. diagrams and hence determine the position from A at
which the S.F. is zero. (b) Determine the value of the B.M. at this point. (c) Sketch
the B.M. diagram approximately to scale, quoting the principal values. [3.32 m, 69.8
