Answer to Question #49488 in Mechanics | Relativity for ndugus

Question

A 1.05 m long rod whose weight is negligible is supported at its end by wire A
and B of equal length. The cross-section area of A is 1.00 mm2; that of B is 4.00
mm2. Young’s modulus of wire A is 2.40 1011 a  P ; that for B is1.60 1011 a  P . At
what point along the rod should a weight W be suspended to produce (a) equal
stress in A and B? (c) Equal strain in A and B?
