A rigid bar AB 9 m long is suspended by two vertical rods at its end A and B and hangs in horizontal position by its own weight. The rod at A is brass: L = 3 m, A = 1000 mm^2, E = 100,000 MPa. The rod at B is steel: L = 5 m, A = 445 mm^2, E = 200,000 GPa. At x distance from A, a vertical load P = 4300 N is applied. a)What is the value of distance x? b)What is the stress at the brass? c)What is the stress at the steel?
