A light rod of length 75 mathrm‌cm is suspended from the ceiling horizontally by means of two vertical wires of equal length tied to its ends. One of the wires of equal length tied to its ends. One of the wire is made of steel of cross section 0.2cm2, and the other is brass of cross section 0.4cm2. The position along the rod at which a weight may be hung to produce equal stress (ysteel=20×1010N/m‌2ybrass=10×1010N/m‌2)
