A steel wire of length 503‾√cm is connected to an aluminium wire of length 60cm and stretched between two fixed supports. The tension produced is 104N , if the cross section area of each wire is 1mm2 . If a transverse wave is set up in the wire, find the lowest frequency for which standing waves with node at the joint are produced . (density of aluminimum =2.6gm/cm3 and density of steel =7.8gm/cm3 ). is connected to an aluminium wire of length 60cm and stretched between two fixed supports.
