Question

A 1.05-m-long rod of negligible weight is supported at its ends by wires A and B of equal length. The cross-sectional area of A is 1.80 mm^2 and that of B is 4.20 mm^2 . Young's modulus for wire A is 2.30×1011 Pa ; that for B is 1.20×1011 Pa .

 

At what point along the rod should a weight w be suspended to produce equal stresses in A and B? (d=? m from wire A)
