Two identical wires of iron and copper with their Young's modulus in the ratio `3:1` are suspended at same level. They are to be loaded so as to have the same extension and hence level. Ratio of the weight is

Two identical wires of materials are joined together and subjected to a force. Their Young's modulus are in the ratio 2 :1 . Then their indidual extensions are in the ratio

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:
