Two rods, A and B, of equal free length are elastic. Both hang vertically 0.6m apart and support a rigid bar horizontally. The bar remains horizontal when a vertical load of 60 KN is applied to the bar 0.2m from A. If the stress in A is 100 MPa, determine the stress in B and the cross-sectional areas of the two rods: EA 200 GPa, E130 GPa.
