3. A beam simply supported on a 12-m span carries a uniformly distributed load of 30 kN/m over the middle 6 m. Using an allowable stress of 130 MPa, determine the lightest suitable beam. What is the actual maximum stress in the selected beam? (Shear and moment diagram are optional) 30 kN/m -3m- -3m- Ḥ 6 m
