Question
Q4. A steel beam of symmetrical I section is shown in Fig Q9. The beam has a mass of 30 kg per meter run and is 9 m long. The beam is simply supported at each end and the maximum bending stress is not to exceed 140 MN/m2 at any point. Calculate EACH of the following:
(a) The maximum uniformly distributed load that can be carried;
(b) The minimum radius of curvature when this maximum uniformly distributed load is carried.
Note: Modulus of elasticity for steel = 210 GN/m2
