A simply supported beam has a span of 3 m. A concentrated load of 30 kN is applied at mid-span gradually. If E = 200 GPa and G = 80 GPa and the beam is of rectangular section (60 mm x 150 mm), find the strain energies stored in the beam (i) due to bending and (ii) due to shear. Also find the deflection under the load.
