The compound beam ADBEC shown in the figure consists of two beams (AB and BC) joined by an internal hinge at B. The loads on the beam consist of a 15 kN force at the midpoint of BC and a uniformly varying load over the 4 m length of the beam AB as shown in the figure. The beam is roller supported at A and fixed supported at C. 15 kN 2 m D * 25 kN/m 2 m E 1.5 m 1.5 m (a) Draw the free body diagram of the member AB (b) Draw the free body diagram of the member BC (c) Determine the support reactions for the member AB (d) Determine the resultant internal loading at cross section through point D (also draw section FBD) Determine the resultant internal loading at cross section through point E (also draw section FBD) (e)
