  • A compound bar consists of two bars of equal length. Steel bar cross-section is 3500 mm2 and that of brass bar is 3000 mm2. These are subjected to a compressive load 100,000 N. If Eb = 0.2 MN/mm2 and Eb = 0.1 MN/mm2, the stresses developed are:


  • Options
  • A. ?b = 10 N/mm2, ?s = 20 N/mm2
  • B. ?b = 8 N/mm2, ?s = 16 N/mm2
  • C. ?b = 6 N/mm2, ?s = 12 N/mm2
  • D. ?b = 5 N/mm2, ?s = 10 N/mm2

  • Correct Answer
  • ?b = 10 N/mm2, ?s = 20 N/mm2
