11.14 (B). A beam of uniform cross-section, with centroid at mid-depth and length 7 m, is simply supported at its ends and carries a point load of 5 kN at 3 m from one end. If the maximum bending stress is not to exceed 90 MN/m² and the beam is 150 mm deep, (i) working from first principles find the deflection under the load, (ii) what load dropped from a height of 75 mm on to the beam at 3 m from one end would produce a stress of 150 MN/m2 at the point of application of the load? E = 200 GN/m² [24 mm; 1.45 kN.]
