A 2 m long light metal rod AB is suspened form the c eiling horizontally by means of two vertices wires of equal length, tied to the ends. One brass and has corss section of `0.3xx10^(-4)m^(2)` and the other is of steel with `0.1xx10^(-4)m^(2)` corss-section. In order to have equal stresses in the two wires, a weight is hung from the rod. The position of weight along the rod from end A should be :

Young's modulus of brass and steel are 10 xx 10^(10) N//m^(2) and 2 xx 10^(11) N//m^(2) , respectively. A brass wire and a steel wire of the same length are extended by 1 mm under the same force. The radii of the brass and steel wires are R_(B) and R_(S) respectively. Then

The Young's modulus of steel is twice that of brass. Two wires of same length and of same area of cross section, one of steel and another of brass are suspended from the same roof. If we want the lower ends of the wires to be at the same level, then the weights added to the steel and brass wires must be in the ratio of:
