Q1: 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
σb = 10 N/mm2, σs = 20 N/mm2
B
σb = 8 N/mm2, σs = 16 N/mm2
C
σb = 6 N/mm2, σs = 12 N/mm2
D
σb = 5 N/mm2, σs = 10 N/mm2
ANS:A - σb = 10 N/mm2, σs = 20 N/mm2 As it is a compound bar strain produced will be the same in both bars... |
