5. A rigid bar AB, 9 m long is suspended by two vertical rods at its end A and B and hangs in a horizontal position by its own weight. The rod at A is brass, length 3m, cross-sectional area is 1000 mm? and E, =1×10°N /mm² . The rod at B is steel, length 5 m , cross-sectional area is 445 mm?. At what distance 'd' from A may a vertical load P=3000N be applied if the bar is to remain horizontal even after the load is applied? Steel 5m Brass 3m P = 3000N A 9m
