Two vertical rods of equal lengths, one of steel and the other of copper, are suspended from the ceiling at a distance `l` apart and are connected rigidly to a rigid horizontal bar at their lower ends. If `A_(S)` and `A_(C)` be their respective cross-sectional areas, and `Y_(S)` and `Y_(C)`,their respective Young's moduli of elasticities, where should a vertical force `F` be applied to the horizontal bar in order that the bar remains horizontal?`
