Theory of Structures A compound bar consists of two bars of equal length. Steel bar cross -section is 3500 mm²and 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: b = 5 N/mm² s = 10 N/mm² b = 10 N/mm² s = 20 N/mm 2 b = 6 N/mm² s = 12 N/mm² b = 8 N/mm² s = 16 N/mm² b = 5 N/mm² s = 10 N/mm² b = 10 N/mm² s = 20 N/mm 2 b = 6 N/mm² s = 12 N/mm² b = 8 N/mm² s = 16 N/mm² ANSWER DOWNLOAD EXAMIANS APP
