A rod of length 1.05 m having negligible mass is supported at its ends by two wires of steel (wire A) and aluminium (wire B) of equal length as shown in the figureThe cross sectional area of wires A and B are `1.0 mm^2` and `2.0 mm^2`, respectivley. AT wat point along the rod should a mass m be suspended in order to produce equal strains in both steel and aluminium wires?
