Problem 1 Two solid cylindrical rods support a load of P = 27 kN as shown below. Rod (1) has a diameter of 16 mm and the diameter of rod (2) is 12 mm. Determine the normal stress in each rod. What diameters should we make the rods if they fail at σ = 130 MPa? 2.5m (1) 4.0 m Ocb = 126.8 MPa 3.2 m P 23 2.3 m
