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________?
Ab = 5 N/mm2 s = 10 N/mm2
Bb = 10 N/mm2 s = 20 N/mm 2
Cb = 6 N/mm2 s = 12 N/mm2
Db = 8 N/mm2 s = 16 N/mm2
Correct answer
B. b = 10 N/mm2 s = 20 N/mm 2
Explanation
The correct answer is b = 10 N/mm2 s = 20 N/mm 2.
