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: (A) b = 10 N/mm2s = 20 N/mm2(B) b = 8 N/mm2s = 16 N/mm2(C) b = 6 N/mm2s = 12 N/mm2(D) b = 5 N/mm2s = 10 N/mm

Description : 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 ... 6 N/mm2 s  = 12 N/mm2 (D) b = 5 N/mm2 s  = 10 N/mm

Last Answer : (A) b = 10 N/mm2 s  = 20 N/mm
