Question
4.12 (A/B). A brass strip, S0 mm x 12 mm in section, is riveted toa steel strip, 65 mm x 10 mm in section, to form
a compound beam of total depth 22 mm, the brass strip being on top and the beam section being symmetrical about
the vertical axis. The beam is simply supported on a span of 13m and carries a load of 2kN at mid-span.
(a) Determine the maximum stresses in each of the materials owing to bending
(b) Make a diagram showing the distribution of bending stress over the depth of the beam.
Take E for steel = 200 GN/m and E for brass = 100 GN/m.
