Two cantilever beams of same length and cross-sectional dimensions carry the same load at their free tip, the first beam made of steel and the second of aluminum alloy. The value of E for steel is 3 times that of aluminum alloy. If the maximum bending stress in the steel beam is o, and in aluminum beam is oa, the ratio of os/ da is (b) 1/3 (d) 1 (a) 3 (c) 1/4 Two cantilever beams of same length and cross-sectional dimensions carry the same load at their free tip, the first beam made of steel and the second of aluminum alloy.
